When Israel escaped from Egypt 3400 years ago, God promised them that none of the diseases of Egypt would afflict them. God could have worked miracles to achieve this promise but instead he gave them a marvellous law of health and hygiene, and knowledge ahead of their time. So much so that we're sure they never understood some of it, but did appreciate that it worked.
In this fortnightly course of 4 sessions several superb examples will be chosen to show that the law of Moses was indeed a law from God.
