With what shall I come before the LORD and bow down before the exalted God? Shall I come before him with burnt offerings, with calves a year old? Will the LORD be pleased with thousands of rams, with ten thousand rivers of oil? Shall I offer my firstborn for my transgression, the fruit of my body for the sin of my soul?
He has showed you, O man, what is good. And what does the LORD require of you? To act justly and to love mercy and to walk humbly with your God.
Micah 6:6-8
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
