Osa dein in the Greek means, "all the things that he saw." In the mysterium book Revelation, the writer begins his work with the assertion he gives a report of all his spiritual guide shows him. Jesus is his guide. John can do little other than get all he sees but this may not be as easy as it looks.
If Jesus is talking, where else would you be looking? I do not think I could take my eyes off HIm to see the events He unfolds. I never see angels, that I know, but one would have my attention. Jesus? I couldn't get enough of Him.
So it that John probably has a good reason to write, "I put down everything I saw." He wants us to know his is a trustworthy record.
To get the message of certainty into an uncertain world, there may have to be three elements. That is, one must have a trustworthy guide, a reliable recipient and a worthwhile message. Jesus is the ultimate trustworthy guide. John goes to some lengths to insist upon his reliability as a scribe. That leaves the message. It must be worthwhile.
What makes a message worthwhile? In part, at least, the message, if it relates to God and man, must not make God evil or man inconsequential.
Consider the modern paradox. Man points with great pride to his discoveries, while each of these discoveries makes man smaller and less significant. Each move of man more fully removes man from his place of prominence, a stop at a time.
Man is a part of nature, the modernists say, but only a part and a part more trivial and dangerous as the years pass. In religion, man can admit his tiny stature, while at the same time minding his status with God, as in Psalm 8:4. In Christian theology, man is not good in the mind and bad in the body. Man and world must be good, for they are God made. Sin mars the connection but cannot disconnect the line between man and God.
The message, to be trustworthy, cannot make man inconsequential.
The message, to be trustworthy, cannot make God evil. Tiny hearts assume the goodness of God, with unlimited power and unblemished nature, ignoring all holocaustic evidence to the contrary to their own peril.
How can man be meaningful and God good, if the earth and so much that happens on it, is so bad?
The message, if trustworthy, will not focus on what is and what is not. The message will focus on what is and what is not in relation to what is not yet. People are hungry but can be fed. Wars occur but peace may come. Diseases ravage but cures can be found. Man lives ignorant of his place with God but he can get to know his place and so find his own consequence in the hands of a good, completely good, God.
Man is inconsequential if he is only natural, limited in and by time and space and only so. If, however, man can stand outside himself, consider himself and see what he is not yet, then no height or breadth or depth of discovery can threaten him. Man is of consequence quite because of his capacity for discovery.
Man's greatest discovery is that he, man, does not create, only discover. Man's greatest discovery will be the moment he discovers the God of the cosmos, who continually leaves clues as to His person and where we might find Him.
