Banners can be a call out for action. They shout out their message in letters written large. Such too has been the role of prophets and evangelists. I wonder whether you have, or have had, the opportunity to speak out for God?
I am sending you to them, and you are to say to them, ‘This is what the Lord GOD says.’ And whether they listen or refuse to listen—for they are a rebellious house—they will know that a prophet has been among them.
What I tell you now in the darkness, shout abroad when daybreak comes. What I whisper in your ear, shout from the housetops for all to hear!
“Go, stand in the temple courts and tell the people the full message of this new life.” Acts 5:20
