Acts 3:19 Repent therefore and be converted.
Becoming a Christian is a once-for-all event, in which we repent of our sins and cast ourselves on Christ alone for our salvation. When we are converted, God takes us "out of darkness into His marvelous Light"
(I Peter 2:9)
But being a Christian is a daily, ongoing experience. It is a lifelong process of daily repentance and faith, turning from sin and seeking to live for Christ, in the power of the Holy Spirit.
That is where our wills come in. Although we have been converted and God has come to live in us, our old nature is still "alive and kicking." Our stubborn wills still demand to put self first instead of Christ.
It isn't easy to bring our stubborn wills into submission to Christ, but when we do, it is as if a misplaced vertebra has snapped back into place. Instead of the stress and tension of a life out of harmony with God, we discover the serenity of His presence.
Who will control your will today? You- or Christ?
