All a man's ways seem right to him, but the Lord weighs the heart. To do what is right and just is more acceptable to the Lord than sacrifice.
Proverbs 21:2-3
Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
Ephesians 6:11-12
