1 Corinthians 13:2
“And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.”
Love is fundamental for the believer. The word "Love" was first used in the book of Genesis 22:2:
“And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of.” This is the time when father Abraham was going to offer up his only son Issac for a burnt offering, or a sacrifice. This was a type and shadow of the sacrifice that would eventually take place at the appointed time, when God offered up his only begotten Son for a sin offering; or as John 3:16 says: “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.” Love has many merits, in Romans 13:10 we learn that “Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.”; meaning, love compels you to uphold what is morally right; thus, you don't lie, murder, fornicate, steal, why? because Love worketh no ill toward his neighbour. The Apostle Peter says: “And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins.” In what way is charity (love) going to cover a multitude of sins? by preventing them; out of love you will see that you walk in the Spirit and not after the flesh, or as Galatians 5 says: “But the fruit of the spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance: against such there is no law.” Why isn't there any law against the fruits of the spirit? because “Love worketh no ill to his neighbour" “Do we then make void the law through faith? God forbid: yea, we establish the law.” -Romans 3:31. That is, we uphold it with Love and obedience to the word of God. The Lord Jesus Christ said: “This is my commandment, That ye love one another, as I have loved you.”
