1 Corinthians 13:4–8 - This is the most well-known biblical description of love:


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

     1 John 4:8 - God  Is  Love   "Whoever does not love does not know God, because God is love."

This equates love with the very nature of God Himself.

     John 3:16 — Love as Sacrificial Giving  >  "For God so loved the world that He gave His one and only Son..."


Love is defined by sacrifice and action, not just feeling.

     John 15:13 — The Greatest Love - "Greater love has no one than this: to lay down one's life for one's friends." 


     1 John 3:18:  Love in Action:  "Let us not love with words or speech but with actions and in truth." 
     Matthew 22:37–39:  The Greatest Commandments:   Jesus summarized the entire law as:

1.   Love God with all your heart, soul, and mind

2.   Love your neighbor as yourself.
