1 John 4:7-11, 20-21
Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God. He who does not love does not know God, for God is love. In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we also ought to love one another.

If someone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen? And this commandment we have from Him: that he who loves God must love his brother also.

1 Corinthians 13
Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal. And though I have the gift of prophecy, and understand all mysteries and all knowledge, and though I have all faith, so that I could remove mountains, but have not love, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, but have not love, it profits me nothing.

Love suffers long and is kind;
love does not envy;
love does not parade itself,
is not puffed up;
does not behave rudely,
does not seek its own,
is not provoked,
thinks no evil;
does not rejoice in iniquity,
but rejoices in the truth;
bears all things,
believes all things,
hopes all things,
endures all things.

Love never fails.

But whether there are prophecies, they will fail;
whether there are tongues, they will cease;
whether there is knowledge, it will vanish away.
For we know in part and we prophesy in part.
But when that which is perfect has come,
then that which is in part will be done away.

When I was a child,
I spoke as a child,
I understood as a child,
I thought as a child;
but when I became a man,
I put away childish things.
For now we see in a mirror, dimly,
but then face to face.
Now I know in part,
but then I shall know just as I also am known.

And now abide faith, hope, love,
these three;

but the greatest of these is love.
