Christ suffered for our sins once for all time. He never sinned, but He died for sinners to bring you safely home to God. He suffered physical death, but He was raised to life in the Spirit.
When I got the revelation that Jesus died for all sin committed by everyone who had lived and will ever live, I was in such awe. It took me a while to chew on that and to let it really sink in. When Jesus died it was for every sin I would ever commit. It still amazes me to think about that.
