8639. A person, for example, who does not know that the Lord is the Saviour of the human race cannot possess faith in Him, worship Him, love Him, or thus do good for His sake. A person who does not know that all good comes from Him is incapable of thinking that his righteousness and his salvation come from Him, let alone of desiring that they should do so, and so is incapable of living from Him. A person who does not know that there is a hell and a heaven, or that there is a life lasting forever, is not even capable of thinking about the life of heaven or of applying himself to receive it. The same is so with all other matters of faith.
