I am the God who forgives your sins and I do this because of who I am and I will not hold your sins against you. Isaiah 43:25
"Once we've confessed our sins to him, it's all forgiven and forgotten and he doesn't even bring up the past. "
When something starts going wrong in your life, do you automatically think, "God's getting even with me, I know it! I did that thing I'm ashamed of yesterday (or last year or twenty years ago) and now he's settling the score."
Does God really treat his children that way? Absolutely not! Isaiah says God doesn't hold our sins against us. Once we've confessed our sins to him, it's all forgiven and forgotten and he doesn't even bring up the past.
If you're a Christian, pay close attention to Ephesians 1:4-5: "Even before the world was made, God had already chosen us to be his through our union with Christ, so that we would be holy and without fault before him. Because of his love God had already decided that through Jesus Christ he would make us his children—this was his pleasure and purpose." (TEV)
Do you realize that when God looks at you, he sees you through Jesus Christ? Jesus Christ on the cross paid for all of your sins so that you're forgiven and they're forgotten.
That's why becoming a Christian is such GOOD NEWS. I give Jesus all my life -- the good, the bad, the ugly - and he takes it and he forgives me and he gives me a new chance. He says, "Now I see you without a single fault. You stand before me covered with my love."
