1 Samuel 4:11

And the ark of God was taken, as a welcome prize; and the two sons of Eli, Hophni and Phinehas, the guardians of the ark, were slain. Thus the Lord gave His people evidence that He had indeed withdrawn His merciful presence from them, in spite of the fact that they had the ark in their camp. This is a serious warning to all who boast of their orthodoxy in a mere fleshly manner. relying upon this fact to give them a standing before God, just as many have the name of Christ in their mouths, but are far from accepting Him as their personal Savior. God wants true repentance, faith, fear of His Word. A dead orthodoxy without true piety of the heart avails nothing.
