'Eternal Life' in the Bible

Search the scriptures; for ye suppose in them ye have eternal life: and these are they which testify of me.

Then Simon Peter answered him, Lord, unto whom shall we go from thee? thou hast the words of eternal life.

even as thou hast given him authority over all flesh, that with regard to all those whom thou hast given him, he should give to them eternal life:

and this is eternal life, that they should know thee the only true God, and him whom thou hast sent, Jesus, the Messiah.
