Reference: This verse follows very closely the passage in 1 Corinthians:
1 Corinthians 13:4-7
4 Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
6 Rejoiceth not in iniquity, but rejoiceth in the truth;
7 Beareth all things, believeth all things, hopeth all things, endureth all things.
There is no question that 1 Corinthians 13:4-7 forms the model upon which Moroni 7:45 is written. Obviously, the same reason for similarity of language exists here as in other occasions where New Testament passages appear in the context of the Book of Mormon text.
