the story in the bible goes like this. Christ suffered the cross and died for our sins. We as sinners were saved because He drank a cup that took on all of our sins, pain,sickness, and death. when He died He sacrificed His perfect life for non perfect people. in the old testament the people would bring sacrifices of animals once a year to the high priest who would then shed its blood on an alter and pray for that families sins. God would accept the sacrifice and then push back their sins for a year. people could not live up to the LAW so God gave us an easier way out. He came as Jesus and lived a sinless life. He was our high priest and provided His own body as the sacrifice. when He was in the grave for those two days He preached to the ones who died before Him in Sheoll( waiting place ) and took the keys to death and hell so only HE could judge. HE rose agian on the third day because the grave couldnt hold Him. He then went to heaven to prepare a place for His people and to come again to judge the world.
