When we think of sin, many times we think only of robbery, murder, adultery, etc. But the Bible tells us that sin is anything that doesn't please God or is a transgression of His law. Anything we do that we shouldn't, like losing our temper or stealing these are sins of commission. Anything we should do but don't, like failing to pray or read the Bible or to truly love our neighbor these are sin of omission. There are not only sins in deed but also sins in word and thought like lying, cursing, lust, pride, and hatred. The Bible says these are all sins.
