And this is the will of him having sent me, that every one seeing the Son, and believing in him, should have eternal life: and I will raise him up at the last day.
But for this was I commiserated, that in me first Jesus Christ might show forth all longsuffering, for a model to them about to believe on him to eternal life.
He believing in the Son of God has the testimony in himself: he not believing God has made him a liar; for he has not believed the testimony which God has testified of his Son.
And we know that the Son of God has come, and has given us understanding, and we know him true, and we are in him true, in his Son Jesus Christ. This is the true God, and eternal life.
