Becoming Mature offers a transformative approach to Christian discipleship using scripture, personal experience, and psychological insights to connect with the reader.

And since y’all are my peeps. Here’s a free preview of the introduction.


Introduction

If you can keep your head when all about you  

    Are losing theirs and blaming it on you,  

If you can trust yourself when all men doubt you,

    But make allowance for their doubting too;  

If you can wait and not be tired by waiting,

    Or being lied about, don’t deal in lies,

Or being hated, don’t give way to hating,

    And yet don’t look too good, nor talk too wise:

If you can dream—and not make dreams your master;  

    If you can think—and not make thoughts your aim;  

If you can meet with Triumph and Disaster

    And treat those two impostors just the same;  

If you can bear to hear the truth you’ve spoken

    Twisted by knaves to make a trap for fools,

Or watch the things you gave your life to, broken,

    And stoop and build ’em up with worn-out tools:

If you can make one heap of all your winnings

    And risk it on one turn of pitch-and-toss,

And lose, and start again at your beginnings

    And never breathe a word about your loss;

If you can force your heart and nerve and sinew

    To serve your turn long after they are gone,  

And so hold on when there is nothing in you

    Except the Will which says to them: ‘Hold on!’

If you can talk with crowds and keep your virtue,  

    Or walk with Kings—nor lose the common touch,

If neither foes nor loving friends can hurt you,

    If all men count with you, but none too much;

If you can fill the unforgiving minute

    With sixty seconds’ worth of distance run,  

Yours is the Earth and everything that’s in it,  

    And—which is more—you’ll be a Man, my son!

~ Rudyard Kipling ~

As a young boy, Rudyard Kipling’s poem If (quoted above) made an indelible mark on my soul. Before I knew Christ, it embodied what I believed maturity would look like. It was the only poster that hung in my room, constantly reminding me of the man I wanted to become. It is no coincidence, I believe, that maturity has been an obsession throughout my life. In hindsight, it was a God-inspired obsession, a heavenly calling. God has given me more understanding since my boyhood days, both through divine revelation and through practical experience.

I would describe my achievements in life as mediocre. I have a checkered history where my personal relationships are concerned. Today I am happily married to a wonderfully on-fire woman of God, and we have a beautifully blended family of five children and one granddaughter. I attribute this outcome solely to the grace of God. (If you knew my story you would too, trust me.)  My children are good kids. I am very proud of the adults they are becoming but none of them are really on fire for God…yet. I have a successful career, currently holding a managerial position at a natural gas company, but I could have achieved more. I can’t say I have won many souls for Christ, nor have I any notoriety in the Christian world. There is only one thing that I have truly excelled at – inner work. I have a dogged commitment to doing the hard, hidden work of maturity.

So let me set your expectations straight upfront: This book is about the unglamourous, unheralded hard work of becoming like Christ that most won’t see and very few will give you accolades for, BUT it is THE MOST important work that you can do, and if you choose to put in the work, your reward will be great indeed.

Excited? Let’s start unpacking it with Romans 8:19 (NLT):

For the creation waits with eager longing for the revealing of the sons of God.

It is significant that in this verse the apostle Paul used the Greek word huios (which is translated as ‘sons’). There are four possible words that he could have used. There is nepios which is a word used to describe an infant. An example of its usage is contained in Hebrews 5:13. Then there is paidion which is a young child as used in Matthew 19:13-14. There is also teknion which describes an adolescent or immature young adult. In the New Testament, it is often used by a teacher to refer to his disciples who have not yet matured. For example, in 1 John 5:21. Finally, there is huios. It is the word used for a mature son. It is the word used to describe Christ as the Son of God, and the word Christ used for Himself when he referred to Himself as the Son of Man.

Therefore, in the context of Romans 8:19, all of creation is not longing merely for more converts to Christianity, but for all the Christian babies, children and teenagers to grow into mature manhood and womanhood. This is what the world is waiting to see, and this is the cause that I have given my life to. My mission is to be an example, a catalyst and a servant in God’s glorious plan for maturing the Bride of Christ into absolute perfection, full authority and dazzling beauty of the fullness of Christ! I too, am eagerly longing for the church (myself included) to grow up into the measure of the stature of the fullness of Christ. I hope it will happen in my lifetime, but even if it doesn’t, I will happily dedicate the rest of my years in service of this vision. Of course, this is not just my vision, this is God’s heart desire for His daughters and sons. He longs for us to come to maturity.

This mission is the reason for this book. My prayer is that you will find practical wisdom here that will help you grow in Christ. This is a book about the how – how we become mature. The contents are the gleanings of my journey toward maturity. I converted to Christianity as a teenager when I became a Roman Catholic through the Rite of Christian Initiation of Adults (RCIA). Then, at twenty-one, I became a born-again believer and got baptized (again) in a non-denominational church with Pentecostal roots. However, I did not begin to see significant growth in my maturity until my late thirties.

What was responsible for this acceleration in my spiritual growth? A God-encounter. Up until that moment I had experienced a lot of religion and a lot of behaviour modification but limited transformation. What I mean is, I was filled with knowledge about God and how a Christian should behave but I had very little (if any) change in my internal desires and motivations.

(To read about my testimony, check out my first book – Authentic Joy).

After my encounter with the liquid love of Jesus, I began to see a change in my life. This was not as a result of my willpower, but through the power of the Holy Spirit, fuelled by His love for me and my love for Him.

This is how it started for me. From that moment, I would meet with my Rabbi every morning with excitement to discover what He wanted to teach me each morning. That was over ten years ago, and it was just the first key to unlocking a life of transformation. On these pages, I will share with you all that I have learned from my successes and my failures on my life’s journey thus far.

TESTIMONIALS


Matik and Tricia,

Thank you so much for a beautiful experience of discovering God’s love. It was so good to learn about the ways in which His love is planted, grows and multiplied in my life.
I thoroughly enjoyed every session and eagerly looked forward to the next one every week.
Each session helped me discover something about God that I hadn’t recognized before. And they showed me something of myself that I hadn’t yet discovered or actually knew but was holding back. Putting these lessons into practice in my life has been and will continue to be life transforming for me.
The wonderful thing is that when I am transformed the people in my life begin a journey also. They may not know it or realize it yet but I know that He who began a good work….
Thank you again for putting into us (me) the way you do.
It makes a difference.
The Lord bless you abundantly.

Much love in Christ

Hello, Matik & Tricia,

First and foremost, thank you for creating a space where I could be open and vulnerable despite the fear I initially felt. It was truly an accomplishment for me to share my thoughts, and I am so grateful for the opportunity to do so.

Throughout this journey, there were times when I didn’t feel like showing up, when I wanted to skip sessions. Yet, my hunger to finish strong, without excuses, pushed me to honor my commitment to myself. I felt compelled to prove that I could make time for me, even amidst the busyness of the day and the emotions I carried.

Your mentorship has had an impact on me in ways I can’t fully express. When I said I felt like I was lost at sea, I meant it. Life’s unexpected challenges—like the loss of my eldest sister and the difficult relationship with my younger brother who seem to battle hatred and anger issues towards our family —had left me questioning everything. There were times when I felt as if I were being targeted, like I was digging myself out of a pit only for the dirt to be thrown back on me.

But through these struggles, I’ve come to understand that although the circumstances were too heavy to bear on my own, I always had the strength to return to the one who promised to be there for me. The class not only encouraged me but also challenged me in ways that forced me to engage with my Bible more deeply. It shouldn’t have taken this class to do so, but I’m grateful that it did. I’ve made a promise to myself to continue strengthening that connection, and I have been making more time for it.

You may not realize it, but on those days, your guidance saved my heart and mind from what felt like an inevitable breakdown.

Thank you once again for all you do. I applaud the message you’re spreading, and I look forward to joining Part 2 next year, God willing.

Warm regards,
Rachel, Trinidad & Tobago


I loved that this was an open place to share. I had quite a bit on my plate at the start, and being in that space was a healing in itself. It renewed my trust in God. At that time, my husband was having some issues with his sight; he couldn’t see. But listening to the teachings and hearing what others had to share helped me to see God’s hand working in my life, and that of my husband, even in that situation.

It seems like there was something happening in my life for each fraction of Part 2, I was having some issues with my alcoholic brother. He was drinking and getting into fights. But being in a place that I felt safe to share and being taught about God’s continued grace, helped me through. During Part 3, I was not in the best place spiritually; I wasn’t giving God His due, not spending enough time in His presence. But Matik’s presentations (practice and
assignments) helped to pull me out of that place and be more focused on my
relationship with God.

I truly believe that spirituality is much more important than religion. I also believe that God isn’t about saving only one religion but all of mankind. These three ‘courses’ reiterated that fact. Interacting with people of different countries, religious persuasions and socio-economic backgrounds, taught me that I take a lot of things for granted in my life.

I truly enjoyed these sessions and looked forward to them. I would this again if given the opportunity, because there was so much to learn that I’m sure I missed something(s).

Thanks so much for this Matik! May God continue to bless your efforts to spread His Kingdom message to others.

Hi everyone. My name is Gillian. My husband and I met Matik and Tricia virtually during our search for a greater level of understanding of the Kingdom of God and desiring a greater daily impact in our lives through a deeper intimacy with God. I have had the great opportunity to sit expectantly through the Spiritual Formation sessions for Part 2 and Part 3 courses.

The Authentic Joy journey has been a real eye opener for me. In their loving way, I was encouraged to ask myself some deep questions, that allowed me to understand who I am and who God created me to be. My fellow course-mates helped in the process by sharing their experiences and what they gleaned as well. I especially liked the exercises and the habits we were encouraged to develop. Journaling is still a challenge but I appreciate the value of it and will settle in one day. Our model was always Christ Jesus and I learnt that real life was thriving in His love, joy and peace and not the false self of the survival mode where I had the tendency to perform for acceptance.

We are all to continue to seek the Kingdom of God and His Righteousness and in this, mature in love and purpose. I encourage you to go on this journey of Becoming Mature. For me although the course has ended, the transformation journey continues. I am committed to ardently pursue intimacy with Father, Son and Holy Spirit. My life depends on it.

Thank you, Matik and Tricia for your passionate pursuit of God and joy in giving this course. I love you both.

This spiritual growth 10 week class through Authentic Joy was extremely well crafted and thorough with the foundational principles of our faith and very helpful and necessary for me, personally, to contemplate the basics and see where things got tangled or bent away from truth. Matik and Tricia provide a warm, safe, authentic atmosphere to ponder together and reflect, and then be encouraged. I was edified so much and it was so affirming to my spirit what God has been teaching me, but took being in community-valuing the Body oneness- to actually believe in it fully. I love the emphasis on valuing community to grow. Also their prayers are SO full of life and powerful. I could have spent the whole time in prayer with them. Their deep relationship with God is so felt. I’m very grateful to have been a part of the class with such good company of other believers!
