Sin sees the world with no God in it. Where we might think of sin as slip-ups or missteps, God views sin as a godless attitude that leads to godless actions. Isaiah 53:6 (NLT) says, “All of us have strayed away like sheep. We have left God’s paths to follow our own.”
A life of doing what we feel like doing, whenever we feel like doing it. God says to love; I choose to hate. God instructs to forgive; I opt to get even. God calls for self-control; I promote self-indulgence.
This is sin. But Jesus took the punishment for that sin and made us whole. Through his bruises we get healed. God has piled all our sins, everything we’ve done that’s a sin on him. So trust his work for you, but then also trust his work in you.
