Revelation 3:10

Because thou hast kept the word of my patience: the doctrine of the gospel is, unquestionably, the word here called the word of the Lord's patience, because it was that word, that doctrine, which (as those times went) could not he adhered to and observed without much patience in those that adhered to it; both actively, waiting for the promises revealed in it, and passively, enduring all manner of trials and crosses. To keep this word, was to keep close not only to the matters of faith revealed in it, but to the duty imposed by it upon ministers and others in the preaching and propagating of the gospel, and all the duties of a holy life. I also will keep thee from the hour of temptation, which shall come upon all the world; for this faithfulness God promises to keep the ministers of this church from those persecutions which raged elsewhere, and were further, in Trajan's time, to come upon all Christians living under the Roman empire. To try them that dwell upon the earth; to try those Christians that lived within that empire, how well they would adhere to Christ, and the profession of the gospel. This I take to be a more proper sense, than theirs who would interpret this hour of temptation of the day of judgment, which is never so called.
