Some people have a view of God that believes he could never be mad. Yet, in both the Old Testament and the New there are many passages which detail the anger and wrath of God upon sinners. God never gets mad without a cause and he never is unjust in his anger. Romans 1:18-32 documents a number of things that reveal the wrath of God from heaven. We should carefully consider these things and if we are practicing them we should immediately repent.
