This Corinthians passage is the most famous biblical wedding reading because it speaks directly of love. This reading can either be just the first paragraph, or both paragraphs may be read.

1st Corinthians - Chapter 13  

Though I speak with the tongues of men and angels, but have no love, I have become as 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.Love suffers long and is kind. Love does not envy. Love does not parade itself, is not puffed up. Love rejoices in the truth. Love bears all things, believes all things, hopes all things, endures all things. Love never fails.
 
But where there be prophecies, they shall fail; where there be tongues, they shall cease; where there be knowledge, it shall vanish away.
For we know in part, and we prophesy in part.
But when that which is perfect is come, then that which is in part shall 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 an adult, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
And now abideth faith, hope, love, these three; but the greatest of these is love.
 
 


"God is love."
 
For many people, this is their favorite passage from the bible and the meaning, "God is Love", sums up their personal relationship with God.

1st John - Chapter 4
 
We read in the first epistle of John,
Let us love not in word or in tongue, but in deed and in truth. And by this we know that we are of the truth, and shall assure our hearts before Him. For if our heart condemns us, God is greater than our heart, and knows all things. Beloved, if our heart does not condemn us, we have confidence toward God.... 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...



Collossians 3:12-17

Therefore, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive whatever grievances you may have against one another. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity. Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. Let the work of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns
and spiritual songs with gratitude in your hearts to God. And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.
