God first expressed this characteristic in the Garden of Eden after Adam and Eve's sin, when He did not destroy the human race as He had a right to do. God was also patient in the days of Noah, while the ark was being built. And God is still patient with the sinful human race; He does not presently judge so as to destroy the world, because He is patiently giving everyone the opportunity to repent and be saved.
