For I am with you, and no one is going to attack and harm you. Acts 18:10.
So long as the Lord had work for Paul to do in Corinth, the fury of the mob was restrained. The Jews opposed themselves and blasphemed; but they could neither stop the preaching of the gospel nor the conversion of the hearers. God has power over the most violent minds. He makes the wrath of man to praise Him when it breaks forth, but He still more displays His goodness when He restrains it; and He can restrain it. “By the greatness of thine arm they shall be as still as a stone, till thy people pass over, O Lord.” (Exodus 15:16)
Do not, therefore, feel any fear of man when you know that you are doing your duty. Go straight on, as Jesus would have done, and those who oppose shall be as a bruised reed and as smoking flax. Many a time men have had cause to fear because they were themselves afraid; but a dauntless faith in God brushes fear aside like the cobwebs in a giant’s path. No man can harm us unless the Lord permits. He who makes the devil himself to flee at a word can certainly control the devil’s agents. Maybe they are already more afraid of you than you are of them. Therefore, go forward, and where you looked to meet with foes you will find friends.
Charles H Spurgeon
