9 ... If ye will not believe surely ye shall not be established.
The foundation of all promises from God is belief. Those who cannot believe through faith "shall not be established." And what is it that we should believe? Keys to belief that will build a foundation were given by Jehoshaphat to Judah and Jersusalem.
20 And they rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Jehoshaphat stood and said, Hear me, O Judah, and ye inhabitants of Jerusalem; Believe in the LORD your God, so shall ye be established; believe his prophets, so shall ye prosper.
