Simple: Jesus bore our sins on himself. How is this possible? We don't know and never will until we go to Heaven. Why? He loved us so much. But it wasn't so much that He, a normal, everyday man bore everyone's sins, it was that He, the ONLY perfect, unsinning, pure, holy, perfect man, who never sinned or committed ANYTHING WRONG bore our sins. He did nothing wrong. God turned away because He was ashamed that His Son was suffering, just as any father would. We have no idea whatsoever, how He can be Father, Son, and Holy Ghost at the same time, but He is. The point is that Jesus is the only pure and perfect sacrifice who died the worst death, on the cross, to save us of our sins. He could do it because He was and is perfect and never sinned. He also was COMPLETELY man and completely God, again, we don't claim to be know-it-alls, we don't know how it works. Because He was completely man, He suffered our pains and temptations. Anyway, there will never be anyone who is perfect, only Jesus.
I must ask however, is this the subject of the topic? It matters, but not here on this forum. Start another topic.
