"If I really do grow up, Lord, I want to grow up and be just like You."
I don't know about you, but I came to faith in a church culture that focused entirely on belief/faith being the defining characteristic of the Christian life. Receiving Christ was a belief that you came to accept. That was what "mattered."
As I matured in the Lord, though, I realized that while that is true to an extent that there is a much larger framework. We don't "just" subscribe to a belief system, but we have been called to live a life for God's glory. Belief is the first step to living as God's children in the world, but that is sustained through the conscious decisions we make and the life that we live. As John Eldredge wrote, "Life is not a problem to be solved; it is an adventure to live."
Jesus calls us to follow Him, to live life the way He did on the path of simple devotion to God. Operating under the thought "life does not consist in an abundance of possessions" (Luke 12:15) we show God's kindness to others as His imitators (Ephesians 5:1). Today let us put our faith into practice by "living in a manner worthy of the Gospel of Christ" (Philippians 1:27).
As Rich loved to say, "Be God's."
