There are things about ourselves that we need to be working on regularly.  We would prefer that God would push a button and do it for us.  It does not happen that way.  We study to increase mental powers and our grasp for truth.  We work on changing habits that produce character.  We discipline ourselves to be true disciples.  There are no shortcuts to these.  Of course, we are workers together with God.  By working with Him, we are being built into persons who reflect the image and likeness of our Lord.

“We then, as workers together with Him also plead with you not to receive the grace of God in vain.” 2 Corinthians 6:1 (NKJV)
