Paul encouraged the Corinthians to live for Jesus, no matter where they found themselves in life when they decided to follow Jesus. Too often we are led to think that we can't serve God from where we happen to be in life. We believe more knowledge is necessary; we don't have the gifts needed to serve God. Or, perhaps we think our life circumstances preclude us from being used by God. Whatever the many reasons we can come up with as to why we can't be used by God, Paul wants to put them to bed. God will use us right where we are - NOW! If we make ourselves available to be used that is.
