What is the Bible's teaching on rationalism?

Rationalism is reliance on human reason for the discovery of truth, with its standard of measure being the human intellect. The rationalist believes only if something can be reasoned out with human logic. However, this method of learning is flawed because it cannot extend beyond the limits of human intelligence. While rationalism has a role in education and discovery, it is of no use in man's attempt to find or know God. In contrast, faith relies on the word of someone trustworthy – and in the things of God, on God speaking in His Word. As the Apostle Paul states in 1 Corinthians 1, God planned for man to find Him through faith alone. The Bible warns that living by rationalism instead of faith can lead to a vacuum in the soul, acceptance of lies, and false doctrines. In Hebrews 11:6, it is stated that only faith can please God, and He can be believed because He never lies and always keeps His Word.
