By this we know that we abide in him and he in us because he has given us of his Spirit. 14 And we have seen and testify that the Father has sent his Son to be the Savior of the world. 15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 So we have come to know and to believe the love that God has for us. God is love, and whoever abides in love abides in God, and God abides in him.
1 John 4:13-16
I’m going to keep this short and sweet. You can’t abide in God and not love your brother. In addition to the scripture above go read 1 Corinthians 13. Now make necessary adjustments. : )
