Many modern people who describe themselves as Christian apparently find it hard to imagine an angry God - but why?
Do they suppose that a loving God would never be angry?
Do they suppose there is an intrinsic conflict between anger and love?
Surely that is absurd!
God is our loving Father - we need to ask whether it is sometimes appropriate for a loving Father to be angry, and to express that anger, and to act (lovingly) upon that anger.
The answer is - yes, of course loving Fathers may appropriately be angry and may act upon that anger.
Nothing more need be said: An angry God? Yes, of course.
