"Although many people believe in God, few understand what faith in Him means, and what they must do to conform to His heart. This is because, although they are familiar with the word 'God' and expressions like 'the work of God', they do not know Him, let alone His work. It is not surprising, therefore, that all those who do not know God have a confused belief. They do not take seriously the belief in Him, because it is too unknown, too strange for them. In this way, they are not up to the demands of God. That is, if people do not know God or His work, they are not fit for Him to use, and still less can they fulfill His desire. 'Belief in God' means believing that there is a God; This is the simplest concept of faith in Him.
