This Epistle was addressed to the same persons as was the first. Its purpose was to strengthen them in view of dangers threatening them within the Church. The apostle addressed them as having ‘like precious faith” with himself. He first reminded them of great principles of preservation. All things pertaining to life and godliness are granted through the knowledge of Him who called them by His glory and virtue. Because of this perfect provision the saints are called to diligence in the development of their resources. Faith is the root principle, and this must be developed until it reaches the ultimate fruitage, which is love.
As the apostle wrote, he was conscious of his approaching departure. He was remembering the glory that had flamed on him on the mount of transfiguration. On that mount he had heard the Lord speak of His exodus. He now used the same word in referring to his own departure. On the mount he had seen the “power” and “coming” of the Lord Jesus, and here he dealt with those two great facts. What he had then seen had confirmed the prophecies of the past, which had been a lamp shining in a dark place.
