In today's culture we define "love" very flippantly. We love hamburgers, we love sports, we also love our spouses and God. Everything is love, love, love. Love however, means so much more according to the true definition of the word. Love is not just a feeling of infatuation, Love is a commitment that you make and according to Scripture....never fails.
"Love never fails..." 1 Corinthians 13:8a
FAILS: G1601- to drop away; be driven out of one's course; to lose, become inefficient:—be cast, fall (away, off), take none effect, to perish; to (properly, to fall from a place which one cannot keep, fall from its position).
Love definition: 1 Corinthians 13:4-8
One does not "fall out of love" - We cannot change the definition of the word to match our behaviors. TRUE love NEVER fails.
Love doesn't stop being patient or kind etc. God defines love because He IS love.
