"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;"
When someone says something or does something we can do one of two things...
1. We can construe that the meant to hurt us, that they are doing something deceptive and are guilty of something bad
2. We can believe that another has good intentions, does not mean to hurt anyone, is innocent of any evil in what they are doing/saying.
Love does not surmise evil, it does not backbite or countenance back biting, it does not dig up past sin, it does not make a man an offender for a word. Even jealousy will not dwell in love, because love trusts others and is not thinking evil of them.
Love will at least hope good of others if it cannot absolutely believe.
