'Eternal Life' in the Bible

You search the Scriptures, for in them you think you have eternal life. And they are the ones witnessing of Me,

Whoever partakes of My flesh and drinks My blood has eternal life, and I will raise him up at the last day.

Then Simon Peter answered Him, Lord, to whom shall we go? You have the Words of eternal life.

And I give to them eternal life, and they shall never ever perish, and not anyone shall pluck them out of My hand.

even as You have given Him authority over all flesh so that He should give eternal life to all You have given Him.
