It is not our performance that makes us mature, but our acceptance of who we are in Christ – Our old way of thing is that if we do right, we will be right and therefore we spend our lives trying to do all the right things, to make ourselves acceptable. But Paul says in Ephesians in his prayer – “that the God of our Lord Jesus Christ, the Father of glory, may give to you the spirit of wisdom and revelation in the knowledge of Him, the eyes of your [understanding being enlightened; that you may know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints” – It is our acceptance of all Christ is that we grow into the full knowledge of God.
