Did you watch the epic TV mini-series The Bible during December?
If you did you will have been reminded of just how much violence the Old Testament records. For the average non-Christian viewer it may reinforce their suspicion that the God of the Old Testament is a God of anger and malevolence, unsuited to our modern morals.
What can we say in response?
It is important to maintain that God is a judge who has the right to dispense judgement. He is the creator, and we are the creation. His judgements are fair and wise by definition. Whether the flood at the time of Noah or the day of judgement when Christ returns, history displays the justice and sovereignty of God.
