7Beloved, let us love one another, for love is from God; and everyone who loves is born of God and knows God. 8The one who does not love does not know God, for God is love. 9By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him. 10In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. 11Beloved, if God so loved us, we also ought to love one another. 12No one has seen God at any time; if we love one another, God abides in us, and His love is perfected in us. 13By this we know that we abide in Him and He in us, because He has given us of His Spirit. 14We have seen and testify that the Father has sent the Son to be the Savior of the world. 15Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. 17By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world. 18There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love. 19We love, because He first loved us. 20If someone says, "I love God," and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen. 21And this commandment we have from Him, that the one who loves God should love his brother also.
