One joy in life for Monica and me at the moment is watching our grandsons grow from little babies to little boys. Each so beautiful. So energetic. So curious. So full of life and learning. So unique.

Some things are predictable, other things not so much. How exciting when they take their first steps. When they speak their first words. Their first tooth. Their first lost tooth! The eldest of our five recently typed in and sent me his first text message. They’re growing up!

But there was also the first surgery. Little worries about speech or sleep or habits we don’t want to see develop. We long for our children to thrive, to grow, to be well-adjusted, healthy, and to become mature. We teach and train them, slowly and (mostly!) patiently. Sometimes it’s two steps forward, one step back. But then something wonderful and wholly unexpected emerges, and we can only express wonder and gratitude at the incredible gifts God has given.

No wonder the apostles Peter and Paul could speak of Christian development in terms of growth from infancy to maturity (e.g. 1 Peter 2:1-3; Ephesians 4:13-15). Spiritual growth can also be messy and unpredictable. It doesn’t happen according to a fixed timeline or schedule. It does not follow a nicely ordered path through a predictable series of steps or phases. Sometimes we progress in spits and spurts, sometimes two steps forward, one step back.

In the case of a child, it is possible to grow old but not really ‘grow up,’ not really become a mature person, responsible and respectful, accomplished and active. The same is true spiritually: it requires a strong intention to become mature, as well as some understanding of what spiritual maturity looks like, and how a Christian might take steps in that direction. And if someone does become mature it is not merely the result of human effort; surely a miracle of grace has also taken place! Only by the work of the Holy Spirit can someone become spiritually mature.

And yet the Bible consistently calls believers ‘to grow in grace and the knowledge of our Lord Jesus Christ’ (2 Peter 3:18). It is clearly God’s intention that his children grow up!

Over the next few issues of the Advocate we will explore some of the patterns and dynamics of Christian growth and maturity. Some things are predictable, even in the midst of all the messy unpredictability. We can mature as hearers of God’s Word, mature in prayer or in service, in virtuous character, in Christian concern for all people, in knowledge or in hope. We hope you will join us as we learn together what it means to become mature in Christ.
