Book of John. In John 5:21, Jesus says "For just as the Father raises the dead and gives them life, even so the Son gives life to whom he is pleased to give it."
Actually, this can be interpreted literally or one can interpret it as:

Yes, God is life. From God comes life as He alone is the Creator.

Jesus gave life through teaching the way back to God.

He reiterates this again in John 10:17-18, "The reason my Father loves me is that I lay down my life-only to take it up again. No one takes it from me, but I lay it down of my own accord. I have authority to lay it down and authority to take it up again." So Jesus claims the authority over both life and death.
Jesus has the power to give up a good life and to receive it again through forgiveness. Just as all sinners can do.

Jesus told the woman at the well "Everyone who drinks this water will be thirsty again, but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life" (John. 4:13-14). He also told a large crowd "For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day" (John 6:40). Here Jesus is telling the crowd that their eternal destiny is in His hands. Notice here that Jesus did not say "My Father will raise him up," instead He says I will raise him up.

Through his teachings.

Ok, I think I have made my point. However, I do have 1 question:

IF Jesus was actually God in the flesh.....then when he was killed, why did he not resurrect himself for all to see so that it would be proven once and for all that he was truly God?
