Again it is contended that Paul predicted that prophecies should cease: "Whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge it shall vanish away." [17] Unfortunately, however, for those who see in this passage a prophecy of the discontinuance of revelation, Paul tells us _when_ prophecy or revelation (for prophecy must needs always be founded on revelation) will cease; that it is not in this mortal life, but "when that which is perfect is come." "For we know in part and prophesy in part; but when that which is perfect is come, that which is in part shall be done away. * * * For now we see through a glass darkly, but then [when that which is perfect is come] face to face. Now I know in part, but then [when that which is perfect is come] shall I know even as I am known." [18] That this refers not to this life, where the best and purest only see in part and know in part, but is to be looked for in that future and perfect existence where men shall see as they are seen and know as they are known, is too obvious to need comment. That prophecy, and the revelation on which it is based, was designed to continue with the saints in this mortal existence is evident from the fact that in the opening verse of the succeeding chapter [19] the apostle admonishes the saints to "follow after charity and desire spiritual gifts, but rather that ye may prophesy." The whole genius of the gospel contemplates continuous revelation in the church; and so far is the Bible from justifying the belief that the time will come when it will cease, that on the contrary it teaches that revelation will increase more and more, especially becoming abundant in the last days. Revelation is the very "rock" or principle upon which the Church of Christ is founded. "Whom do men say that I the Son of Man am?" was the abrupt question which Jesus once put to his disciples. The answers given were varied. "But whom say ye that I am?" Then Peter answered: "Thou art the Christ the Son of the living God." "Blessed art thou Simon Barjona," was the Lord's reply, "for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say unto thee, that thou art Peter, and upon this rock will I build my church; and the gates of hell shall not prevail against it." [20] That is as if the Master had said: "Blessed art thou Simon, for flesh and blood hath not revealed unto you that I am Christ, the Son of the living God, but my Father which is in heaven; and I say unto thee, Peter, upon this principle of revelation will I build my church, and the gates of hell shall not prevail against it."
