Blessed is the one who reads the words of this prophecy, and blessed are those who hear it and take to heart what is written in it, because the time is near.The first of seven blessings in Revelation is directed to two sets of people. First, the blessing is for the person who reads the words of this prophecy aloud to others. Reading in ancient times was almost always done aloud. Manuscripts were rare, and there were almost always those who would like to hear what was written. Today, Bibles are common, but still many don’t know what is written between the covers. It would still be good today if those who read the Scriptures always did so with the intent of sharing what they read with others. The one who reads and shares the message of Revelation is blessed in his deed.
-- Rev 1:3 NIV
Second, the blessing is for those who hear and “take to heart” what is written. While certainly taking the message to heart is important, this translation does not capture fully the response required for blessing. The ones who are fully blessed hold on to what they hear; that is, they remember it. They do even more. They are also moved to obey its exhortations, commands, and warnings. The blessed one who hears Revelation says with the Psalmist,
I have hidden your word in my heartDo you read Revelation with intent to share? Do you listen to its words intending to remember and obey them? If so, you will be blessed.
that I might not sin against you.
-- Psalm 119:11 NIV
