It’s good to make assumptions if the assumption is that a person’s motives are good; it’s sinful to make assumptions if the assumption is that a person’s motives are bad. When we look at other Christians—their beliefs, their words, their deeds—love calls us to assume the best rather than the worst. Love calls us to regard them with hope rather than suspicion. Out of love for God and our brothers and sisters, we ought to grant them the same mercy, the same grace, the same hope we grant ourselves.
