Whenever the enemy tries to remind you of your failures and past, raise that blood-stained banner; remind him of JESUS’ victory.
It is written: And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death. Revelation 12:11
…for though the righteous fall seven times, they rise again, but the wicked stumble when calamity strikes. Proverbs 24:16
Christ makes all things new, His blood washes clean.
