Isaiah 53:6. Christ suffered for us as punishment for our sin. God let Christ suffer for our sins because he loves and desires to save us from the destructive consequences of our sin. The essence of sin is being in disobedience to God. When we go astray and turn away from God to go our own way, we are in sin. God will punish all sin. It is his nature.
Romans 1:25. Many of us may worship God for a season, but then we make wrong choices by putting other things above God. When we lust and worship things above God, we are basically idol worshiping. God made it part our human nature to worship. The problem is that instead of worshiping God we will worship the other woman, our job, our car, or even ourselves.
Romans 1:25. Our sin nature continues to ask the question, is there a God, because we want to be disobedient to God. We desire to be wise and define what is right and wrong (Romans 1:22, "Professing themselves to be wise, they became fools").
