The same is true of my Christian walk. Every time I submit to the will of God, I stretch a little. Every moment I spend in the presence of God, I stretch even more. On my knees, stretch, in the word, stretch, serve others, stretch, deny myself, stretch.
Even though it appears I am stretching, changing, and growing as a result of these things, in reality, just like Stretch Armstrong, I can’t stretch myself. Only God can stretch me. Only God can change me.
And we, who with unveiled faces all reflect the Lord's glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is the Spirit. 2 Corinthians 3:18 (NIV)
