Ezekiel 18:25

Yet ye say, The way of the Lord is not equal. Hear now, O house of Israel; Is not my way equal? are not your ways unequal?

Yet ye say, The way of the Lord is not equal. Their plea for saying "The way of the Lord is not equal," was that God treated different classes in a different way. But it was really their way that was unequal, since, living in sin, they expected to be dealt with as if they were righteous. God's way was invariably to deal with different men according to their deserts.
