Not sure how you could have missed the following...
1Jn 4
7 Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. 8 Whoever does not love does not know God, because God is love.
12 No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us. 13 This is how we know that we live in him and he in us: He has given us of his Spirit.
20 Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen. 21 And he has given us this command: Anyone who loves God must also love their brother and sister.
1 Jn3 9 No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. 10 This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.
15 Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
17 If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person?
