I am responsible for my life, and my sins, death on the cross will not prevent my physical death. I am asked to repent and sin no more, and my soul is what is eternal, and that soul, after physical death, through Faith that Jesus and God are one, begotten from God, born into mortal flesh, to give humanity a chance to redeem itself. Yes, the Jews did offer sacrifices of animals to please God, but it is clearly stated in Isaiah that is not what is pleasing, ""To what purpose is the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats." Having Faith in God in Christ, and by repentance and adjustment of my life according to God's law, my immortal soul will dwell in that dimension we call Heaven, with HIM. It is not like magic, it requires me to live a Godly life, it requires true redemption and to ask for mercy, I am not magically absolved from everything I do because I say "I am a Christian with Faith". This can get theologically thorny, because there are many who state deeds and actions do not help anyone get closer to God. But the act of loving my neighbor and offering charity to the widow and orphan, to feed the hungry and visit the prisoner, is also in the Bible. I have read the Gospel of Thomas, I know that Peter's name was Simon, Jesus changed Shimons name to Peter, as it meant The Rock. Yes, I am aware of the theory that Jesus was taken down alive, it was written in a book called The Passover Plot. My Dad read that, and he was a smart man, he thought it was Jewish propaganda. 75 other books? Nah, that's okay, deeply reading scripture takes years, religion is practice. Practicing Faith causes a shift in consciousness, and God in Christ ceases to be an abstract, it becomes an experience, one can experience God!
