4 because everyone who is fathered by God conquers the world.
God Has Given Us Eternal Life in the Son
And this is the victory which has conquered the world: our faith. 5 Now who is the one who conquers the world except the one who believes that Jesus is the Son of God? 6 This is the one who came by water and blood—Jesus Christ, not with the water only, but with the water and with the blood. And the Spirit is the one who testifies, because the Spirit is the truth. 7 For there are three that testify, 8 the Spirit and the water and the blood, and the three are in agreement.
9 If we receive the testimony of people, the testimony of God is greater, because this is the testimony of God that he has testified concerning his Son. 10 (The one who believes in the Son of God has the testimony in himself. The one who does not believe God has made him a liar, because he has not believed in the testimony that God has testified concerning his Son.) 11 And this is the testimony: that God has given us eternal life, and this life is in his Son. 12 The one who has the Son has the life; the one who does not have the Son of God does not have the life.
Our Assurance of Eternal Life
13 These things I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life.
