The same Jesus shall return as he leftActually, Billy, Jesus was God made FleshJesus was also fully human, and had the free will to make a choice. He decided with both aspects that we were worth the price.
Jesus was always God (eternal). He was born flesh and blood, i.e. fully human, through the Holy Spirit. He died and rose again the third day (another 3). No flesh and blood shall enter heaven, so he was resurrected as new flesh and bone. This is what happens to the faithful.
