I think this is a question we humans have been asking ourselves for many thousands of years. And I also think how we answer this question is very much determinative of our general worldview and how we conduct our lives. In other words, it is not simply an abstract, philosophical question: it has a direct bearing on the here and now.
You may have heard the expression, “You are like the God you worship”. I think there’s a lot of truth in this saying. In other words, if you believe in an aggressive, warlike God, you are quite likely to exhibit aggressive, warlike behaviour; conversely, if you believe in a compassionate, peace-loving God, you are quite likely to direct your efforts towards achieving peaceful and non-violent coexistence with your neighbours in this world.
The Old Testament is, in many ways, an argument or debate between those with different answers to the question, “What is God like?” Through the Torah and the historical books, the wisdom writings and the prophets, we find competing images of God: some depict him as a punctilious law-keeper determined to mete out punishment at the slightest offence; some paint him as a warrior God who protects his servants but is merciless to his enemies; yet others portray him as a God of endless compassion and mercy whose patience never runs out.
The question is, which of these depictions of God is right? What is God really like?
