If someone says he is wonderful and powerful, it should be verified by his deeds. Many, many people, especially women have been deceived through the ages by smooth talk, only to find out later that there can be a discrepancy between talk and walk. Talk is cheap.
The same thing applies to God. If He revealed Himself as wonderful and powerful through words alone, it would be foolish to believe Him. That is the miracle of the Bible. It abounds with historical details of God's supernatural deeds with and for individuals and nations. In Romans 15:4 we read: 'For everything that was written in the past was written to teach us....' God teaches and demonstrates to us in history what kind of God He is. He puts His hand where His mouth is. His words are accompanied by deeds. Without that there would be no compelling reason to believe Him. The following are some examples:
- He promised Abraham the land of Canaan as an inheritance. It was a process that can be followed through thousands of years. The descendants of Abraham went to Egypt where they became a nation. After 400 years of slavery, God brought them out, and they invaded Canaan and took possession of it. Not obeying the covenant which they made with God, He allowed them to be exiled. Afterwards He brought them back (the books of Ezra and Nehemiah). Again they sinned (by rejecting Jesus) and they were scattered to different countries. In 1948, after the establishment of Israel as the official country of the Jews, they came back to their promised land. These are historical facts that can be investigated.
- God says He is merciful, and it is demonstrated by how He forgave the Israelites when they made a golden calf and worshipped it as the god who brought them out of Egypt (Exodus 33). He proved that He is merciful by leading them into the promised land.
- He says He is a God who hears, and proves it by listening to the prayers of Hannah for a child (1 Samuel 1). He cares for the individual.
- He says He loves the Gentiles and not only the Jews, and proves it by sending Peter to the Roman official to tell them the good news of salvation (Acts 10).
History can be investigated. We don't know anything about Joshua's family, but we know he led the Israelites into the Promised Land. It is a fact that most parts of the Bible's history have been well researched. Archaeology has found that many of the towns and cities mentioned in the Bible did exist. The Hittites, Assyrians, Babylonians and other nations are not just names mentioned in the Bible. Their existence and dynasties are well documented and museums have many artifacts for those nations, like the Pharaohs of Egypt and the Herods in the time of the New Testament.
When we come to the Koran and Muslims claim that their book is the superior revelation, we want words and deeds. It contains many words, but has no historical deeds that can be researched. Allah is supposed to be wonderful, merciful and gracious. That might be so, but where are the historical deeds that he did in Arabia to prove it? We do not accept the Koran's references to Biblical incidents. If Allah is superior to the Father of Jesus Christ, He should demonstrate it by giving a better historical revelation. As Muhammed lived in Arabia, we expect an Arabian revelation. The Koran cannot do that, so Allah relies on human support to defend him, especially through violence. We hear that Christian churches in countries like Ethiopia and Egypt have been burnt down by Muslims. People are condemned to death for saying anything against Muhammed or Allah. If Allah is all powerful, surely he would not need puny humans to fight for his honor. If Mohammed brought a true message, people would have listened, like in Jesus' case. There are always doubters, but for a true God, that is no problem. It is no reason to employ the sword to force one's ideas on others.
If a person dares to say anything about the Koran, like the recent burning of the Koran and the resultant killing of personnel in Afghanistan, he is in danger of his life. What does it matter if anybody burns a Bible or a Koran? God and Allah can defend themselves, and their existence is not dependent on people protecting them. There is a big difference between the responses of Christians when God or the Bible is insulted, and Muslims when Allah or the Koran is insulted. Can it be because Allah did not support his words by deeds?
