"He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty." (Psalm 91: 1)
We dwell under the shadow of the Almighty today because of Jesus, our Savior, our Mercy Seat.
In a few verses down, the Psalmist explains specifically the source of this shadow:
"He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler." (Psalm 91: 4)
These wings and the feathers speak of the Mercy Seat:
"17And thou shalt make a mercy seat of pure gold: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof. 18And thou shalt make two cherubims of gold, of beaten work shalt thou make them, in the two ends of the mercy seat. 19And make one cherub on the one end, and the other cherub on the other end: even of the mercy seat shall ye make the cherubims on the two ends thereof. 20And the cherubims shall stretch forth their wings on high, covering the mercy seat with their wings, and their faces shall look one to another; toward the mercy seat shall the faces of the cherubims be." (Exodus 25: 17-20)
The mercy seat represents the place where man's sins are paid for:
"And Aaron shall bring the bullock of the sin offering, which is for himself, and shall make an atonement for himself, and for his house, and shall kill the bullock of the sin offering which is for himself: 12And he shall take a censer full of burning coals of fire from off the altar before the LORD, and his hands full of sweet incense beaten small, and bring it within the vail: 13And he shall put the incense upon the fire before the LORD, that the cloud of the incense may cover the mercy seat that is upon the testimony, that he die not: 14And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times." (Leviticus 16: 11-14)
Today, Jesus is our Mercy Seat:
"Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;" (Romans 3: 25)
"1My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." (1 John 2: 1-2)
"For he shall give his angels charge over thee, to keep thee in all thy ways." (Psalm 91: 11)
We can rest assured that His angels watch over us, because just as Satan used this verse to tempt Jesus to throw Himself off the temple, so to we can know that even if we do fall, we are borne up by His angels, because we are in Christ today (1 John 4: 17)
Today, when you need help, you can rest assured that Jesus, your Savior, Your Mercy Seat, has got you covered.
