New American Standard Bible (NASB)
1 John 4
21 And this commandment we have from Him, that the one who loves God should love his brother also.
1 John 5
1 Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him.
2 By this we know that we love the children of God, when we love God and observe 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-our faith.
5 Who is the one who overcomes the world, but he 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. It is the Spirit 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 men, the testimony of God is greater; for the testimony of God is this, 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 given concerning His Son.
