Cast down every thought that rises up to bring you into condemnation, and then position yourself under the protection and strength of spiritual truth. These thoughts against yourself are counterproductive to your spiritual growth and well-being. If there is truly a need to repent do so, but do not allow yourself to get stuck in things of the past. What's done is done, says the Lord. 1 John 3:20 For if our heart condemns us, God is greater than our heart, and knows all things.
