Love is without end, and it will never leave you or forsake you, because honest love, is as genuine as the Giver, It is a gift and not from from this world, but sent from above. 

It flows naturally & genuinely from the heart and meant to stay, to grow, to endure, to last. It is strong enough to endure all things, it will hope & believe the best of all things. It grows stronger during a trial or trouble, it doesn't break, grow weak at the seams, or fall apart. It endures and wins out in the end, because when it's right & true, it is strong enough to last forever.  It simply will not die.

A person who loves like this, will lay down their own life for the one they love, and would die for them if necessary.

 If you really want the truth, the true & honest to God definition of love that lasts,

it's in the Bible (1 Corinthian 13:4-8) These verse is a good measure to know the truth about a person or a relationship whether it is genuine, you can put a persons' name or your own name in the place of the word "love", as a test for purity of the heart.

A love like this, is pure from the heart and will never leave you...EVER

Anything else less has weak points, and will eventually fail, and will always have an end...
