Our sufficiency is from God

The human person is obviously characterised by series of inadequacies and limitations. Is there anyone able to keep all of God's commandments without any fault and by himself worthy of and deserves God's redemption, salvation and blessings? What's is our relationship with God in Christ Jesus? Christ Jesus has fulfilled the demands of the law and since it's in him we live and move and have our being, we have been made God's adopted children and co-heirs with Jesus Christ. BY THIS FACT OUR SUFFICIENCY COMES FROM GOD.
