Psalm 139:23-24 Search me, O God, and know my heart; test me and know my thoughts. See if there is any wicked way in me, and lead me in the way everlasting.
Isaiah 55:6-8 Seek the Lord while he may be found, call upon him while he is near; let the wicked forsake their way, and the unrighteous their thoughts; let them return to the Lord, that he may have mercy on them, and to our God, for he will abundantly pardon. For my thoughts are not your thoughts, nor are your ways my ways, says the Lord.
Hebrews 4:11-12 Let us therefore make every effort to enter that rest, so that no one may fall through such disobedience as theirs. Indeed, the word of God is living and active, sharper than any two-edged sword, piercing until it divides soul from spirit, joints from marrow; it is able to judge the thoughts and intentions of the heart.
