What is love?

In Peter's epistle, we read: 'Above all, love each other deeply, because love covers a multitude of sins' (1 Peter 4:8) 

Here is another verse that I like too.
If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal.
 1 Corinthians 13:1 

And I mustn't forget this one:
7Beloved, let us love one another, because love comes from God. Everyone who loves has been born of God and knows God. 8Whoever does not love does not know God, because God is love.9This is how God’s love was revealed among us: God sent His one and only Son into the world, so that we might live through Him.…
1 John 4:8

What is love then? When we go at a wedding, we often hear those verses about love. You may have heard them before, you may not!

4Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres. 8 Love never fails.

It's a definition of the perfect love! (1 Corinthians 13:4-8)
