Ha ha! Dear, the key words were “for us”. Adam and Satan had their parts in delivering sin to us in the mail, but only Jesus became sin for us when He died on the cross so we could become the righteous of God, as stated in 2 Corinthians 5:21. It’s not that we become God, but Jesus applies His righteousness to us so that our sin is taken away. That is a treasure not to be taken for granted! Now, your final question before your first checkpoint is this: what do we call the time when all Christians will be judged for what rewards they should receive for what they did in life?
