2. The action which the Seer is commanded to take with the roll receives adequate explanation. He was to _take it_ out of the hand of the strong angel and to _eat it up_. The meaning is obvious, and is admitted by all interpreters. The Seer is in his own actual experience to assimilate the contents of the roll in order that he may know their value. The injunction is in beautiful accord with what we otherwise know of the character and feelings of St. John. The power of Christian experience to throw light upon Christian truth and upon the fortunes of Christ's people is one of the most remarkable characteristics of the fourth Gospel. It penetrates and pervades the whole. We listen to the expression of the Evangelist's own feelings as he is about to present to the world the image of his beloved Master, and he cries, "_We_ beheld His glory, glory as of the only-begotten from the Father;" "Of His fulness _we_ all received, and grace for grace."[238] We notice his comment upon words of Jesus dark to his fellow-Apostles and himself at the time when they were spoken, and he says, "When therefore He was raised from the dead, His disciples remembered that He spake this; and they believed the word which Jesus had said."[239] Finally, we hear him as he remembers the promise of the Spirit of truth, who was to instruct the disciples, not by new revelations of the Divine will, but by unfolding more largely the fulness that was to be found in Christ: "Howbeit when He, the Spirit of truth, is come, He shall guide you into all the truth: for He shall not speak from Himself; but what things soever He shall hear, these shall He speak: and He shall declare unto you the things that are to come. He shall glorify Me: for He shall take of Mine, and shall declare it unto you."[240] Everywhere and always Christian experience is the key that unlocks what would otherwise be closed, and sheds light upon what would otherwise be dark. To such experience, accordingly, the contents of the little roll, if they were such as we have understood them to be, must have appealed with peculiar power. In beholding judgment executed on the world, the believer might need only to stand by and wonder, as Moses and Israel stood upon the shore of the Red Sea when the sea, returning to its bed, overwhelmed their enemies. They were safe. They had neither part nor lot with those who were sinking as lead in the mighty waters. It would be otherwise when judgment came upon the Church. Of that Church believers were a part. How could they explain the change that had come over her, the purification that she needed, the separation that must take place within what had hitherto been to all appearance the one Zion which God loved? In the former case all was outward; in the latter all is inward, personal, experimental, leading to inquiry and earnest searchings of heart and prayer. A book containing these things was thus an appeal to Christian experience, and St. John might well be told to "eat it up."
