So the Philistines were subdued… – 1 Samuel 7:11, 13

The tribes had assembled unarmed to worship. The Philistines, hearing of their gathering, suspected a revolt. A rising was not at that time contemplated, though no doubt there was lurking in the hearts of the people a hope that they would somehow or other be delivered. Hearing that the people had come together, the Philistines determined to attack them; to attack the company who had come together for worship. The people were alarmed; naturally they might be. Samuel, however, the prophet of God, was equal to the occasion. He bade them bring a lamb. I do not know that the lamb was offered according to the Levitical rites, yet prophets in all ages had a right to dispense with ordinary laws. He takes the lamb, puts it on the altar, offers it, and as it smokes to heaven he offers prayer. The voice of man is answered by the voice of God; a great thunder dismays the Philistines, and they are put to rout.

Brethren, if we have done anything for Christ, if we have achieved any victories, if in this house any souls have been converted, any hearts sanctified, any drooping spirits comforted, bear witness that it has been all through the Lamb. And when we have preached Christ ascending up on high, leading captivity captive, and when we have glorified in the fact that He ever liveth to make intercession for us, and that He shall come to judge the quick and dead, if any good has been accomplished it has been through the Lamb-the Lamb slain, or else the Lamb exalted. ~ C.H. Spurgeon
