God knows you — inside and out. Stop trying to lie to God. Stop trying to hide your thoughts, or convince Him of your intentions.
Instead — admit your wrongdoings, ask for forgiveness, invite Him to look at your heart, your motivations, and your desires, and allow Him to mold and shape you into the person He’s designed you to be.
(Psalm 139:23-24) Search me, O God, and know my heart. Examine me, and know my anxious thoughts, and see if there be any offensive way within me, and lead me in the way everlasting.
