To me this verse means that you should declare with you mouth and share the love and truth of God. If you do you will be saved and will prosper. The main idea of this verse is to share Gods word with everyone you come in contact with. I love this verse because to me it means that he will love us no matter what, and he will keep his faith in us. This verse applies to me  because it shows me that he loves me and sometimes people lose faith.
