Do I need a passport for heaven?

Imagine, I have prayed to Allah my whole life. I have done all the things needed for my religion. I’ve even been to Mecca, and here come these people living in our village that are saying that nothing can save you. Nothing that you have done yourself can save you. We are all lost in our sin. One day I was sitting with John (one of the people that had come to our village) and asked him; “Do we need a passport to go to Heaven?” John replied: “Yes, in a sense we do. The passport that we need has to be signed by the blood of the greatest sacrifice ever brought in this world. That is the only way we can enter into Heaven and stay with God for ever.” There is no need for another sacrifice. This is the sacrifice that was brought to take away all our sins. Praise God, He was the one that brought this sacrifice for us.
