The love that God speaks of in the Bible is not just an emotion. It is not just a feeling that is contingent on whether the other person is acting in the manner that pleases us. True love is unconditional. The Word of God defines love for us from Genesis to Revelation. He created us in his image.
Love is an action.
If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
