Some people say that we know that the Bible is God's word by the fact that its teachings are not something that man would want to come up with. For example, the Bible presents man as totally depraved, which goes against man's tendency to think of himself as a good person. The Bible teaches that salvation is by grace alone, which is contrary to man's idea that salvation is accomplished by his own effort. God saves sinners. All other religions teach that man can save himself. If man created a god in his own image, it would not be like the God of the Bible. What do you think of this kind of proof?
