1 John 5:11

“And these will go away into eternal punishment, but the righteous into eternal life.”

so that whoever believes will in Him have eternal life.

and I give eternal life to them, and they will never perish—ever; and no one will snatch them out of My hand.

and the life was manifested, and we have seen and bear witness and proclaim to you the eternal life, which was with the Father and was manifested to us—

By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.

In this is love, not that we have loved God, but that He loved us and sent His Son to be the propitiation for our sins.

These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life.

And we know that the Son of God has come, and has given us understanding so that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
