Because Adam COULD die is PROOF HE WAS NEVER IMMORTAL

Since the time God made man he has always been mortal. The immortality men seek only comes by the new birth and the subsequent resurrection through faith in Jesus Christ. These are things the Bible clearly teaches. And things the false doctrine of original sin and sin nature must flatly reject. Come find out the truth from God's word. And come to know the God you say you love. And the one and only true God our Creator who surely loves you.
