“A Christian is not a man who never goes wrong, but a man is enabled to repent and pick himself up and begin over again after each stumble–because the Christ-life is inside him, repairing him all the time.”—CS Lewis

“Therefore do not let sin reign in your mortal body so that you obey its evil desires… but rather offer yourselves to God as those who have been brought from death to life… For sin shall no longer be your master, because you are not under the law, but under grace.”

Romans 6:12-14

“Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.”

Philippians 3:13-14

“Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.”

2 Corinthians 4:16-18
