Faith in the Incarnate Son of God

5 Everyone who believes^(A) that Jesus is the Christ^(B) is born of God,^(C) and everyone who loves the father loves his child as well.^{(D) 2} This is how we know^(E) that we love the children of God:^(F) by loving God and carrying out his commands. ³ In fact, this is love for God: to keep his commands.^(G) And his commands are not burdensome,^{(H) 4} for everyone born of God^(I) overcomes^(J) the world. This is the victory that has overcome the world, even our faith. ⁵ Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.^(K)

⁶ This is the one who came by water and blood^(L)—Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth.^{(M) 7} For there are three^(N) that testify: ⁸ the^[a] Spirit, the water and the blood; and the three are in agreement. ⁹ We accept human testimony,^(O) but God’s testimony is greater because it is the testimony of God,^(P) which he has given about his Son. ¹⁰ Whoever believes in the Son of God accepts this testimony.^(Q) Whoever does not believe God has made him out to be a liar,^(R) because they have not believed the testimony God has given about his Son. ¹¹ And this is the testimony: God has given us eternal life,^(S) and this life is in his Son.^{(T) 12} Whoever has the Son has life; whoever does not have the Son of God does not have life.^(U)
