What strange tools the Carpenter of Nazareth used to shape a Simon into a Peter! His instruments of change were fish, roosters, pigs, and ordinary people like his wife, his brother, and even his mother-in-law. Shaped by adversity and hammered by time and circumstance, "The Rock" was chiseled into shape on the workbench of this world. 

What tools will God's carpenter use to get us into spiritual shape? He gives us, as He gave Peter, the privilege and capacity to cooperate in the process. He has the power to change us as He did Peter.
