Exodus 28:42 instructs Moses to cover the nakedness of the Priests. “You shall make for them linen undergarments to cover their naked flesh.” The priests must wear these when they approach God’s presence “lest they bear guilt and die.” (Vs 43)
This reminds us the first consequence of the first sin. In Genesis 3:7 we read, “then the eyes of both of them were opened, and they knew that they were naked; they sewed fig leaves together and made themselves loincloths.” They could not bear to stand before God with their naked guilt. So God provided a covering for their guilt by the sacrificial death of a lamb.
John the Baptist pointed Jesus out as “the lamb of God who takes away the sins of the world.” Jesus becomes our “linen undergarment” which enables us to enter into God’s presence.
The Psalmist joyfully sings, “How happy is the one whose transgression is forgiven, whose sin is covered!” (Psalm 32:1)
You see, only happy people can enter into God’s presence!
