Growing as healthy Christians
From Eugene Peterson's Living the Message
It is both natural and appropriate to be excited about a person's conversion. It is the most significant event in life--to be born anew, to be a new creature in Christ. But that significance and the excitement accompanying it do not excuse ignorance and indifference to the complex process of growth into which every Christian is launched via this new birth. Because growth involves so much--so much detail, so much time, so much discipline and patience--it is common to dismiss it and turn over attention to something we can get a quick handle on; the conversion event. Evangelism crowds spirituality off the agenda. But having babies is not a vocation; parenting is. It is easier, of course, to have babies. But a church that refuses or neglects the long, intricate, hard work of guiding its newborn creatures into adulthood is being negligent of most of what is in Scripture.
You've had a tast of God. Now, like infants at the breast, drink deep of God's pure kindness. Then you'll grow up mature and whole in God.1 Peter 2:2
