The apostle was well qualified to speak of the purposes of God concerning the human race; for during the earthly ministry of Christ he had seen and heard much that pertained to the kingdom of God. “We have not followed cunningly devised fables,” he reminded the believers, “when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. For He received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount.”
Yet convincing as was this evidence of the certainty of the believers’ hope, there was another still more convincing in the witness of prophecy, through which the faith of all must be confirmed and securely anchored. “We have also,” Peter declared, “a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.”
While exalting the “sure word of prophecy” as a safe guide in times of peril, the apostle solemnly warned the church against the torch of false prophecy, which would be uplifted by “false teachers,” who would privily bring in “damnable heresies, even denying the Lord” (2 Peter 2:1). These false teachers, arising in the church and accounted true by many of their brethren in the faith, the apostle compared to “wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.” “The latter end is worse with them,” he declared, “than the beginning. For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.” ...
Not all, however, would be ensnared by the enemy's devices. As the end of all things earthly should approach, there would be faithful ones able to discern the signs of the times. While a large number of professing believers would deny their faith by their works, there would be a remnant who would endure to the end.... “Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless.”—The Acts of the Apostles, 534-536. RC 221
It is one thing to treat the Bible as a book of good moral instruction, to be heeded so far as is consistent with the spirit of the times and our position in the world; it is another thing to regard it as it really is—the word of the living God, the word that is our life, the word that is to mold our actions, our words, and our thoughts. To hold God's word as anything less than this is to reject it. And this rejection by those who profess to believe it, is foremost among the causes of skepticism and infidelity in the youth. Pr 319
