(18-19) I testify unto every man that heareth. — Omit “For,” and read, I testify to every one that hears... The “I” is emphatic; it introduces the final warning; the revelation must not be tampered with. If any one shall have added to them, God shall add to him the plagues which are written in this book; and if any one shall have taken away from the words of the book of this prophecy, God shall take away his portion from the tree of life, and out of the holy city which are written (or printed) in this book. We may compare Deuteronomy 4:2; Deuteronomy 12:32. The words are a solemn protest against the spirit which handles rashly or deceitfully the word of God; which adds its own thoughts, or makes its wishes the parent of its interpretations; which dilutes the force of its warnings, or impoverishes the fulness of its promises. The right of continual access to the tree of life was the promise of Revelation 22:14; this right or freedom is forfeited by those who deal falsely or faithlessly by the words of Christ here. In a minor degree, it is true that those who leave this book unstudied and unprayed over, lose much spiritual sustenance and comfort. How much more do they lose who trifle with it, ignore its spiritual teachings, and sin against the laws of that kingdom whose progress it so vividly portrays.
