1Th 4:7 For God has not called us to impurity but to live in holiness.
Paul’s first reason looks forward to the prospect of future punishment, but his second reason looks back to the purpose for which God called each Christian to Himself. God’s plan for a Christian includes purifying his life. Sexual immorality frustrates the purpose of God’s call. Certain pagan cults promoted unclean ceremonies, but Christ’s plans for a Christian are to clean him up. A holy life demonstrates God’s supernatural power at work overcoming what is natural, and it glorifies God.
