they touch the peace that flows through the heart that rests on that imperishable foundation. "Great peace have they that love Thy law, and nothing shall offend them." "The Word of our God shall stand forever." "All flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away; but the Word of the Lord endureth forever. And this is the Word which by the gospel is preached unto you." (1 Pet. i. 24, 25.) [2] In referring to infidel writers, we should bear in mind that by far the most dangerous of such are those calling themselves Christians. In our young days, whenever we heard the word "infidel," we at once thought of a Tom Paine or a Voltaire; now, alas! we have to think of so-called bishops and doctors of the professing church. Tremendous fact! Here we have the same precious golden link again. The Word which has reached us in the form of glad tidings is the Word of the Lord which endureth forever; and hence our salvation and our peace are as stable as the Word on which they are founded. If _all_ flesh is as grass, and _all_ the glory of man as the flower of grass, then what are the arguments of infidels worth? They are as worthless as withered grass or a faded flower; and the men who put them forth and those who are moved by them will find them to be so, sooner or later. Oh, the sinful folly of arguing against the Word of God--arguing against the only thing in all this world that can give rest and consolation to the poor, weary human heart--arguing against that which brings the glad tidings of salvation to poor lost sinners--brings them fresh from the heart of God! But we may perhaps here be met by the question so often raised, and which has troubled many and led them to fly for refuge to what is called "the authority of the church." The question is this: "How are we to know that the book which we call the Bible is the Word of God?" Our answer to this question is a very simple one--it is this: The One who has graciously given us the blessed book can give us also the certainty that the book is from Him. The same Spirit who inspired the various writers of the holy Scriptures can make us know that those Scriptures are the very voice of God speaking to us. It is only by the Spirit that any one can discern this. As we have already seen, "the natural man receiveth not the things of the Spirit of God; ... neither can he know them, because they are spiritually discerned." If the Holy Spirit does not make us know, and give us the certainty that the Bible is the Word of God, no man or body of men can possibly do it; and on the other hand, if He does give us the blessed certainty, we do not need the testimony of man.
