God Weighs Your Motives
All the ways of a man are clean in his own sight, But the LORD weighs the motives.
Proverbs 16:2

We must be wary of our tendency to rationalize our bad behavior. That's what we do when we substitute false explanations for true reasons, when we cloud our actual motives with a smoke screen of nice-sounding excuses.
— Charles R. Swindoll
