When I was a kid I loved to play baseball. We didn’t need an official team, we played whenever we could get 4 or 5 guys together. Since there was very little traffic on our street, we’d play there yelling “Car!” when necessary.
One day I was at bat and I hit that hardball on a line drive to left field. But the ball kept going and going. It went through our neighbors picture window at the front of their house and came to rest after bouncing off of and breaking their TV set.
I did not have the wherewithal to make it right with them. I had no money, no skills, nothing. My dad stepped in and made it right with them for me. He took the responsibility for my actions and bought them a new picture window and TV. This would have been impossible for me.
In the same way Jesus took the responsibility of the sins of the whole world. Some might say well and good, after all, He made us, he had to do it. But like in the story with my dad, my dad could have said, “Steve, you blew it. I’m going to teach you a lesson here. You make it right with the neighbors and buy them a TV and a new window.” In an earlier era, I could have been sold into slavery to pay off the debt. My dad was not obligated to solve my debt for me, and it was not his fault. Neither was it Jesus’. It was for love that he became responsible for our actions and paid our debt.
Our debt was to justice. We have a loving God who made a moral universe. The day will come when judgment will happen to all.
