Love…endures all things. – 1 Corinthians 13:7

The last victory of love is in enduring all things, by which I understand a patient perseverance in loving. This is perhaps the hardest work of all, for many people can be affectionate and patient for a time, but the task is to hold on year after year. I have known some men earnestly check their temper under provocation, and bear a great many slights, but at last they have said, “There is an end to everything: I am not going to put up with it any longer. I cannot stand it.” Blessed be God, the love that Christ gives us endureth all things. As His love endured to the end, so does the love which the Spirit works in us endure to the end.

(L)ove holds out under all rebuffs. “You mean that I shall not love you, my good man, but I shall love you. You give me the rough side of your tongue and make me see that you are not a very lovable person, but I can love you notwithstanding all. What? Will you do me a further unkindness? I will oppose you by doing you a greater kindness than before. You said a vile thing about me; I will not hear it, but if it be possible I will say a kind thing of you. I will cover you up with hot coals till I melt you; I will war against you with flames of love till your anger is consumed. I will master you by being kinder to you than you have been unkind to me.” What hosts of misrepresentations and unkindnesses there are; but if you go on to be a true Christian you must endure all these…Stand fast in love; endure not some things, but all things, for Christ’s sake; so shall you prove yourself to be a Christian indeed. ~ C.H. Spurgeon
