In “Christian Growth After Baptism,” John Mulligan reminds us that baptism is a true beginning point—like arriving at an airport that brings you to a new destination. God cleanses the past, but He doesn’t leave us there; the call is to go forward. New Christians need clarity on what “forward” looks like, and longtime Christians need the same reminder because we’re not coasting to Zion—we’re still marching. Scripture gives direction for that journey, addressing not only what we do, but why we do it: our motives, attitudes, priorities, and affections. We are always under construction, and God’s work in us is both necessary and good.
The central emphasis is character. Jesus begins the Sermon on the Mount with the Beatitudes (Matthew 5), placing the weight of discipleship on the inside—developing the kind of heart God has always desired for His people. These are qualities that shape how we respond (humility, mourning, meekness), how we act (hungering for righteousness, showing mercy), and how we influence (pure in heart, peacemakers, enduring persecution, living as salt and light). This isn’t instant holiness after baptism, but lifelong refinement—choosing a better response when we’re provoked, pursuing righteousness over being “right,” and seeking peace instead of fueling conflict. The world is repelled by hypocrisy, but it is drawn to consistent, humble people who admit failure, get back up, and live for God’s glory.
Colossians 3 then presses the urgency of that pursuit: since we’ve been raised with Christ, we set our hearts and minds on things above, where Christ reigns. Our affections shift, our thinking is redirected, and we become increasingly uncomfortable with the old life we left behind. We remember where our life is headed—hidden with Christ now, and destined to appear with Him in glory—so we refuse to live for temporary “trivial pursuits.” Christian growth means blasting away what belongs to the old nature and building what reflects our Creator. The takeaway is simple but demanding: don’t settle for “just who you are.” Jesus accepts us as we are, but He will not leave us there. The work begins in the everyday places—on the road, at home, with coworkers, with neighbors—where real character is formed as we continually choose the things above.
