Revelation 1: (New King James Version)

Revelation 1:1-3
Introduction and Benediction
1 The Revelation of Jesus Christ, which God gave Him to show His servants—things which must shortly take place. And He sent and signified it by His angel to His servant John, 2 who bore witness to the word of God, and to the testimony of Jesus Christ, to all things that he saw. 3 Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near.

Commentaries:
And Laodicea.
This book is the Revelation of Jesus Christ; the whole Bible is so; for all revelation comes through Christ, and all relates to him. Its principal subject is to discover the purposes of God concerning the affairs of the church, and of the nations as connected therewith, to the end of the world. These events would surely come to pass; and they would begin to come to pass very shortly. Though Christ is himself God, and has light and life in himself, yet, as Mediator between God and
man, he receives instructions from the Father. To him we owe the knowledge of what we are to expect from God, and what he expects from us. The subject of this revelation was, the things that must shortly come to pass. On all who read or hear the words of the prophecy, a blessing is pronounced. Those are well employed who search the Bible. It is not enough that we read and hear, but we must keep the things that are written, in our memories, in our minds, in our affections, and in practice, and
we shall be blessed in the deed. Even the mysteries and difficulties of this book are united with discoveries of God, suited to impress the mind with awe, and to purify the soul of the reader, though he may not discern the prophetic meaning. No part of Scripture more fully states the gospel, and warns against the evil of sin. (Rev 1:4-8)
