2 Corinthians 7:1 (a) This refers to the growth in grace and godliness of the child of GOD. He should halve the desire to be as near like CHRIST as it is possible for a redeemed sinner to be.
Ephesians 4:12 (a) This indicates clearly that the believer is to grow in usefulness and fruitfulness. The Lord does not want us to drift along and make no progress in our ability to serve Him wisely and intelligently.
