Charles Spurgeon Commentary 2 Thessalonians 2:15

"So then, brethren, stand fast, and hold the traditions which ye were taught, whether by word, or by epistle of ours." — 2 Thessalonians 2:15 (ASV)

Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.

"The things which we have handed out to you, which you have been taught, whether by word, or our epistle." They had heard Paul preach; he had not only written to them, but he had also spoken to them; and he instructed them to treasure up what he had said and what he had written, and hold it fast as for dear life. The apostle did not preach what he afterwards left, as the ostrich leaves its eggs; but he watched over it, and he watched over the people who had heard it, anxious that the truth to which they had listened should prove in them to be the message of everlasting life.

Oh, my dear hearers, are there not still some of you who have heard our gospel, to whom we have often and long spoken, and yet, nevertheless, it has not yet been the message of eternal life to you, though it has been to many others? God have mercy on you, and still bring you to the feet of Jesus! As for others who come to listen to the Word for the first time, may it be the power of God to salvation on the very first occasion of their hearing it, to the praise of God, and the glory of his Son!
