Feeling? I would have to disagree there. If it is only a feeling it will pass and often does...It is a commitment for life. When you feel like you are in love and yes even times when you don't feel like it. Love is working through the difficult times with an eye on making your marriage last to honor God and your spouse, your children ect. It is also sharing in the joys of life such as a new baby, promotions or whatever. It is however NOT just a feeling and perhaps that is part of the problem, we make it something it isn't. Lets look at 1 Corinthians as the standard of love. Many unbelievers still use this verse in their weddings and tell me where feelings are mentioned.
Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. 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. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; Rejoiceth not in iniquity, but rejoiceth in the truth; Beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. (1 Corinthians 13:1-8 KJV)
