Psalms 19:14 Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer.
2 Corinthians 10:5 Casting down IMAGINATIONS, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity EVERY THOUGHT to the obedience of Christ;
Psalms 139:2 Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
Proverbs 23:7 For as he thinketh in his heart, so is he:
This truth is aimed at me as well as you. God has forgiven me for a lifetime of sins, a boatload of sins committed before I was saved and after. I cannot number the times I have thought selfish and sinful thoughts. Reading these promises should melt all of our hearts with gratitude for God’s forgiveness:
1 John 1:7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from ALL SIN. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from ALL UNRIGHTEOUSNESS.
C.S. Lewis offered this advice to a friend, still worth heeding as much as possible: "We must learn by experience to avoid either trains of thought or social situations which for us (not necessarily for everyone) lead to temptations. Like motoring (driving) — don't wait till the last moment before you put on the brakes, but put them on, gently and quietly, while the danger is still a good way off."
