Stephen’s preaching was more than they could stand. He was bold. He knew God and the truth. He stood and preached.
They felt that if they could silence him that the problem would go away. They killed him.

Our God is a great God and His work will not be stopped. We just have to be willing to be sacrificed for His cause and His glory.
