The bible

[ThereisaGod]

I know that they were written after but isn't that kind of self explanatory since his death was a fulfillment of prophecy. If it was written before there would have been no way to know that it was full filled. Also his death was what marked the actual start of the new law. This was first preached on the day of Pentecost. Some people dont realize that there is an old law and new law. Before there were the resources of of mass communication there was a need of miracles and things of that nature to spread the word. After Christ was born and grew he gave only them these gifts to prove he is real. After his death he was resurrected as was prophesied setting the new law standards. acts 2:38 - Then Peter said unto them, repent and be baptized everyone of you in the name of Jesus Christ for the remissions of sins, and ye shall receive the gift of the Holy Ghost. In being baptized we are baptized into Christ death and brought out to walk a newness of life (romans 6:1-9).
