These verses show what an impression had been made in other places by the success of the gospel at Thessalonica. Wherever Paul went, he heard it spoken about. In every place men were familiar with all its circumstances; they had heard of the power and assurance of the missionaries, and of the conversion of their hearers from heathenism to Christianity. It is this conversion which is the subject before us. It has two parts or stages. There is first, the conversion from idols to the one living and true God; and then the distinctively Christian stage of waiting for the Son of God from heaven. Let us look at these in order. The Apostle, so far as we can make out, judged the religions of heathenism with great severity. He knew that God never left Himself without a witness in the world, but God's testimony to Himself had been perverted or ignored. Ever since the creation of the world, His everlasting power and divinity might be seen by the things He had made; His law was written on conscience; rain from heaven and fruitful seasons proved His good and faithful providence; yet men were practically ignorant of Him. They were not willing, in fact, to retain Him in their knowledge; they were not obedient; they were not thankful; when they professed religion at all, they made gods after their own image, and worshipped them. They bowed before idols; and an idol, says Paul, is nothing in the world. In the whole system of pagan religion the Apostle saw nothing but ignorance and sin; it was the outcome, in part, of man's enmity to God; in part, of God's judicial abandonment of men; in part, of the activity of evil spirits; it was a path on which no progress could be made; instead of pursuing it farther, those who wished really to make spiritual advance must abandon it altogether. It is possible to state a better case than this for the religion of the ancient world; but the Apostle was in close and continuous contact with the facts, and it will take a great deal of theorising to reverse the verdict of a conscience like his on the whole question. Those who wish to put the best face upon the matter, and to rate the spiritual worth of paganism as high as may be, lay stress on the ideal character of the so-called idols, and ask whether the mere conception of Zeus, or Apollo, or Athene, is not a spiritual achievement of a high order. Let it be ever so high, and still, from the Apostle's ground, Zeus, Apollo, and Athene are dead idols. They have no life but that which is conferred upon them by their worshippers. They can never assert themselves in action, bestowing life or salvation on those who honour them. They can never be what the Living God was to every man of Jewish birth--Creator, Judge, King, and Saviour; a personal and moral power to whom men are accountable at every moment, for every free act.
