Read and keep the words
Charles Box on Rev 1.1-3:
John said, “Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand.” (Revelation 1:3) He said, “Blessed is he that readeth.” It is a blessing to be permitted to read the Revelation of God. This may be a reference to public reading because the next statement has to do with those “that hear the words of this prophecy.” We learn God”s will by reading, hearing, studying and meditation. Those who have the opportunity to become acquainted with God”s revelation are highly favored. The readers and hearers must also “keep those things which are written therein.” None can be right with God who does not obey those things that are their duty. The psalmist said of God”s commandments, “Moreover by them is thy servant warned: and in keeping of them there is great reward.” (Psalms 19:11) Our heavenly hope is in knowing and doing the will of God.
We just don’t realize how blessed we are to have many good versions and tools to understand the Word of God. People don’t take advantage of them. And still it comes down to knowing and doing. Knowledge alone is nothing.
