Self-justification is the natural human default — we evaluate ourselves with a bias toward approval. But God's assessment is not self-reported; He weighs the heart directly. This is both a warning against moral self-deception and a reminder that we need God's perspective, not just our own.
Memory phrase: God sees every heart.
Talk about it: Can we always trust ourselves to know if we are right?
Prayer: God, show me where I am wrong.
