God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
A sin is anything that violates the moral law of the universe. Any time we do what God tells us not to do or fail to do what God commands us to do, we commit a sin. And every time we sin, we are found guilty in the sight of God and deserve divine judgment.
For us as sinful men and women, prayer is not designed to align God with our will, but to align our will with God. Prayer is not to make God more like us but to make us more like God. It should firm up the muscles of our faith.
