2 Peter 1:18

And this voice which came from heaven we heard when we were with Him in the holy mount.

That Peter had not forgotten the commission of the Lord given to him on the shores of the Sea of Galilee is shown in the solicitude which he here displays for the spiritual welfare of his readers: Therefore I shall be careful that you be reminded concerning these things, although you do know them and are established in the truth which is present with you. That was the conception which Peter had of his pastoral office, as it should be the idea of every true pastor, to make it his care, his business, ever and again to remind the believers of all these facts concerning their justification and sanctification. It is true, indeed, the Christians have learned these facts, they know them, but it remains true at the same time that they cannot learn them too well and that the eagerness of the true Christian to hear the fundamental truths over and over again will not diminish. They were established in the truth of the Gospel, they were firmly grounded in the fundamental doctrines of Christianity as they concerned their spiritual life, but they needed the strengthening influence of the apostolic admonition from day to day. Note: We need a better realization of these facts in our day, when so many professing Christians are showing the symptoms of spiritual satiety, which almost invariably is the forerunner of spiritual decay.

The apostle now repeats his statement and gives a reason for the urgency of his appeal: But I consider it proper, as long as I am in this tabernacle, to stir you up by such reminding, knowing that swift is the folding up of my tabernacle, even as our Lord Jesus Christ has revealed to me. While Peter had life and breath, while the Lord continued to add to the days of his life, he considered it the right and proper thing for him to do to keep right on with his reminding and admonishing, to keep the minds of his readers awake to the wonderful glories of the Gospel and to the obligations which accompanied these privileges. He compares his body to a tent, or tabernacle, giving but a weak and temporary shelter to his soul. He knew that it would not be long before the Lord would cause him to fold up his tent; his body, which had so long housed his soul, would be claimed by death. This the Lord had revealed to him, the reference probably being to the incident on the shore of the Sea of Galilee, John 21:18. Here is an instance of true faithfulness, since Peter did not wait idly for the death which, he knew, was soon to come, was imminent, as he expresses it, but continued his work with unabated vigor and diligence, the care of the souls being his chief concern to the last.

But he is looking forward also beyond the immediate future: But I shall use diligence that you also after my departure may always be able to call these things to mind. Not only for the present, and while his own life lasts, is Peter solicitous for the spiritual welfare of his readers, but he also wants to make it his business to have them keep the truth after his death. That is one of his reasons for writing this letter, to have it serve as a permanent reminder of the doctrine which he taught them. Whenever they were in need of definite, authentic information as to the truth, they had but to consult this letter, have their memory refreshed, and thereafter could be all the surer in their Christian life.

That the Christians should not feel the slightest hesitation about accepting the doctrine which Peter taught them is shown in the next verses: For we did not follow cleverly constructed fables in making known to you the power and appearing of our Lord Jesus Christ, but we mere made eye-witnesses of His majesty. What Peter and the other apostles had taught, also in the congregations of Asia Minor, was not a system of spiritual fables cleverly invented to bring them into subjection, after the manner of many false teachers; he was not writing down any human speculations and philosophies in giving them the proper information concerning the power and advent of Christ the Lord, of His return at the end of time, when He will be clothed with full majesty and power, in order to establish His kingdom forever. What Peter had been teaching with regard to this one fact was the truth, for which he could vouch with all the power at his command because he had been privileged to be an eye-witness of the glorification, of the majesty, of Christ.

The apostle states to which event he has reference: For He received from God the Father honor and glory when a voice was borne to Him of such a kind from the sublime Glory, This is My beloved Son, in whom I am well pleased. That was the culminating incident in the happening on the Mount of Transfiguration, Matthew 17:1: Mark 9:2. Jesus, the poor, despised Prophet of Nazareth, who had come into His own and His own received Him not, was invested with honor and glory from His heavenly Father Himself. For while the three disciples, Peter, James, and John, were still lying upon the ground, almost stupefied by the miraculous brightness which surrounded them from heaven, they nevertheless could hear plainly the words which came down out of the cloud, the voice of God Himself, acknowledging Jesus as His true Son, His beloved Son, upon whom His good pleasure rested in full measure. Concerning this Peter testifies: And this voice, borne from heaven, we heard when we were with Him on the holy mountain. Although the mountain was not in itself holy, this wonderful manifestation of the sublime, the splendid glory of God, sanctified and hallowed it for the time being. What Peter means to emphasize in this connection is this, that they, to whom was vouchsafed such a wonderful manifestation of the glory of God, were reliable witnesses, and therefore their Gospel could and should be accepted without question as the truth of the Lord. Mark: This is one of the reasons why we also accept the Gospel as recorded by the apostles as the truth, because God would hardly have revealed Himself in such a manner to men that were hypocrites and swindler,
