Psalm 145:4-7, 11-13
4 One generation will commend your works to another; they will tell of your mighty acts.
5 They will speak of the glorious splendor of your majesty, and I will meditate on your wonderful works.
6 They will tell of the power of your awesome works, and I will proclaim your great deeds.
11 They will tell of the glory of your kingdom and speak of your might,
12 so that all men may know of your mighty acts and the glorious splendor of your kingdom.
13 Your kingdom is an everlasting kingdom, and your dominion endures through all generations. The LORD is faithful to all his promises and loving toward all he has made.
This Psalm speaks of the divine pattern of spreading the fire by telling of God's mighty acts, awesome works and great deeds.
When promoting revival in the local church it is always helpful to recount stories of past advances and victories. The history of revivals is full of examples of local awakenings being ignited by retelling what God did somewhere else with other believers.
Whether by books, pamphlets, letters or by the spoken word, retelling the stories imparts understanding, inspires faith and creates hunger for God to move in similar ways in the hearers' world.
