1 John 5:1-12 New King James Version (NKJV)
Obedience by Faith
5 Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him. 2 By this we know that we love the children of God, when we love God and keep His commandments. 3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome. 4 For whatever is born of God overcomes the world. And this is the victory that has overcome the world—[a]our faith. 5 Who is he who overcomes the world, but he who believes that Jesus is the Son of God?
The Certainty of God’s Witness
6 This is He who came by water and blood—Jesus Christ; not only by water, but by water and blood. And it is the Spirit who bears witness, because the Spirit is truth. 7 For there are three that bear witness [b]in heaven: the Father, the Word, and the Holy Spirit; and these three are one. 8 And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one.
9 If we receive the witness of men, the witness of God is greater; for this is the witness of [c]God which He has testified of His Son. 10 He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son. 11 And this is the testimony: that God has given us eternal life, and this life is in His Son. 12 He who has the Son has [d]life; he who does not have the Son of God does not have life.
