People are sometimes accused of having selective memory. Maybe that’s because we were made in God’s image.
The Lord Himself told Jeremiah that He remembers our sins no more. That’s an interesting statement coming from the One who knows every detail of the universe. No doubt it’s an intentional act on His part, not an indication that He’s lost interest (or that age has set in.)
I don’t recommend selective memory for spouses at anniversary time. But when it comes to God and my sins, I’m fine with it.
