Zechariah 1:10–11 (NKJV)
10 And the man who stood among the myrtle trees answered and said, “These are the ones whom the Lord has sent to walk to and fro throughout the earth.”
11 So they answered the Angel of the Lord, who stood among the myrtle trees, and said, “We have walked to and fro throughout the earth, and behold, all the earth is resting quietly.”
There is a phenomenon called "tunnel vision" with which any aviator who has flown high performance aircraft is intimately familiar.
When a pilot is pulling high "g's" (being pushed down into his seat by inertial forces) the blood supply to the brain is hindered and his vision is affected. His peripheral vision will decrease and an effect similar to this image will develop. Overall acuity will suffer but it will be most pronounced from the outside-in. If he continues to increase the g-forces he can lose his sight and "black out." With training, however, the "focusing" effect will not prevent him (or her) from flying effectively and in a dog-fight this condition is more or less constant. If the aircraft is not continuously pulling "g's" it is probably losing the fight.
There are other occasions though where a similar type of "tunnel vision" occurs. It happens when a person feels "drawn in" to what lies in front of them. The peripheral vision becomes blurred in the resulting concentration on a subject and it is quite possible for a "canopy" like quiet or darkness to steal over their soul. They are so focused that other sounds or sights seem to shrink into the back ground or disappear altogether. A person can experience this on a quiet walk when a sense of peace descends on the soul and the hustle and bustle of life is, for a moment, just gone.
Walt Whitman spoke of this:
''Why are there trees I never walk under but large and melodious thoughts descend upon me?'' Walt Whitman (1819-1892), U.S. poet. "Song of the Open Road," sct. 7 (1856).
It's good, on occasion, to allow the idea that overall things are "OK" to settle in. The angels reported to the Lord that the earth was resting quietly... even though the people of God were still enslaved in Babylon. God replies, a little later, that He was "a little angry" (from our perspective, a huge understatement... since He wiped out the nation of Israel in His wrath), but that very statement reminds us that He is in control... that the apparent chaos is exactly that - apparent- not absolute. There are still breezes whispering through the leaves, soft filtered light warming the path and invigorating coolness to lift the spirits. God is still in His heaven and, in spite of everything, all is still right with the world.
"Don't panic... I've got this!" He whispers to the attentive ear. Yes, there are very discouraging things going on. Yes, Satan seems to be having a field day in some quarters. Yes, the mindless preoccupation of men with their own foolishness can appear overwhelming, and yes, pain and suffering are always with us.
But you, O Man, let that uproar and clamor fade away from your vision. Fix your eye on the path in front of you and see the beauty that is there. It is there... look and see. I have marked out the way... I have provided all that you need to walk it... there is peace to be had, refreshment in due time and encouragement at every turn. Let this be your vision and your hope.
My angels are still walking the earth... they still report that all is going according to My plan... Take a deep breath of the cool air and continue on your way.
