Who is Jesus? Over 2,000 years ago Jesus was crucified in Israel for saying that "He is the son of God." Unfortunately at that time they didn't know any better that they were indeed crucifying "the son of God."
The nature of man is that we have both good and evil in us, which in God's eyes is not acceptable in heaven. Jesus came to take away our sins so that we could all be accepted into heaven. He paid the price for man's sins. That is why I love him so much, because he loved me even before I could ever know him.
