Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood, The Cross is not the emblem of Christianity. If that's all that Christ did was die, we believers would have the penalty paid for our sins and wouldn't have to suffer in hell for eternity, but we would not live again. Sin sends a person to hell forever.
Sin also kills the body soul and spirit.
Christ's death on the Cross, eliminated our going to hell, but it didn't give us everlasting life. The grave cannot hold us no more than it could hold Christ. The Cross is not the emblem of Christianity. The finished work of Christ is the Empty Tomb . The Lord, Himself, gave us the appointed emblems of Christ- Ianity, and that is the Bread and Cup at the communion table.
