「你們聽見號聲時，眾百姓要大聲呼喊，城牆就必塌陷，百姓個個都要往前直上。」－約書亞記6:5
在「主許多寶貴的秘密」一書中，信心的呼喊必定是最為珍貴的。
耶和華曉諭約書亞說：「看哪，我已經把耶利哥和耶利哥的王，並大能的勇士，都交在你手中。」
耶和華在這裡不是說：「我將要把...」，祂乃是說：「我已經把...」。耶利哥城已經是以色列人的了，但現在的問題是：要如何取得呢？看似癡人說夢，但卻實實在在，是出於耶和華的口。
沒有人會覺得，光是呼喊就能使城牆倒塌，然而這正是他們得勝的秘訣。
這不是一般的呼喊，這乃是出於信心的呼喊，這是一個在勝利顯得多麼遙不可及的時候，單單照著神的話，向神求取應許之勝利的信心。於是，神果真照著他們的信心為他們成就了；當他們一呼喊，城牆就立即倒塌。
神已經聲明，祂已經將耶利哥城交給他們了，於是信心毫不猶豫的當真。
幾個世紀之後，聖靈將這信心得勝的一役，記在希伯來書中：「因著信，耶利哥的城牆被圍繞七日，就倒塌了。」

"And when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall ascend up every man straight before him" (Joshua 6:5).The shout of steadfast faith is in direct contrast to the moans of wavering faith, and to the wails of discouraged hearts. Among the many "secrets of the Lord," I do not know of any that is more valuable than the secret of this shout of faith. The Lord said to Joshua, "See, I have given into thine hand Jericho, and the king thereof, and the mighty men of valour." He had not said, "I will give," but "I have given." It belonged to them already; and now they were called to take possession of it. But the great question was, How? It looked impossible, but the Lord declared His plan.
Now, no one can suppose for a moment that this shout caused the walls to fall. And yet the secret of their victory lay in just this shout, for it was the shout of a faith which dared, on the authority of God's Word alone, to claim a promised victory, while as yet there were no signs of this victory being accomplished. And according to their faith God did unto them; so that, when they shouted, He made the walls to fall.
God had declared that He had given them the city, and faith reckoned this to be true. And long centuries afterwards the Holy Ghost recorded this triumph of faith in Hebrews:
"By faith the walls of Jericho fell down, after they were compassed about seven days."--Hannah Whitall Smith.
