It’s not a matter of God having a short memory, it’s the fact that when it comes to my sin He has amnesia. He has forgotten my sins; blotted them out; and, according Psalm 103:12, He has “removed our transgressions as far as the east is from the west.” God has done more than forgive my sins, He has forgotten them.
Listen to how Isaiah describes the work of God on our behalf: “Come now, let us reason together, says the LORD: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool (Isaiah 1:18).”
When God forgives you and forgets your sins, he changes your relationship with Him. He sees you as justified, glorified, and purified because of the sacrificial death of Jesus.
Because God gas forgiven and forgotten, He freshens: “If anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new (2 Corinthians 5:17).”
Here’s the good news: If your life is a mess, confess and profess. When you confess your sin, and profess Jesus as your Savior, God will bless.
