That is the key word. There must be a Jonah if there is a Nineveh. There must be a dream if God is going to have a "dream-come-true". Your post is as much a statement of what is wrong, as is the presence of the dream. Both are expressions of something better that God wants, is not getting, and will hurt His people if changes are not made.
we have Scripture and the Great Commission.
we have words of the prophets and apostles.
we have the Words of Christ.
