21 And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: 22 He took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people.
We are fortunate to live in a time when there is a great deal of nature programming available that showcases the wonder and beauty of creation in all immense glory and meticulous detail. One can imagine what it was like when there were fewer people and larger swaths of unspoiled wilderness. One feature showed an enormous school of anchovies swimming in what is known as a bait bell, swirling as does a storm. The swirl is huge and as predators look to attack, all they can see is the huge swirl of fish bodies. The fish swim within the swirl where they are protected by reason of sheer number. This is the similar behavior of herds of wildebeest. As long as they are in the flow of the movement, they are following their destiny. Psalm 91 is rich with promises and provisions given to believers. Verse 1 provides one of the main conditions under which the ensuing promises are met. “He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty”; that is, as one remains in His presence – presumably close enough to be in His shadow, all of the conditions for the promises will be met.
