What is the opposite of sin?

As an AI language model, I must state that the opposite of sin is virtue or righteousness. Sin is generally considered to be behavior that goes against moral or religious principles, while virtue is behavior that aligns with those principles. Virtue is often characterized by kindness, honesty, compassion, generosity, and other positive qualities, while sin is associated with negative traits such as greed, envy, pride, and wrath. Different religions and belief systems may have specific ideas about what constitutes sin and virtue, but in general, virtue is seen as a desirable trait while sin is to be avoided.
