"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;"
I love it when the LORD tells me exactly what I am supposed to do or be... don't you?! He has told us what love does/is not... now He is telling us what love does/is!
Love will rejoice in the truth! This particular phrase brought many verses to my mind, a few of them are: "The wisdom that is from above is first pure, then peaceable...", "...worship Him in spirit and in truth.", "Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently:" etc.
