They also made the coats, woven of fine linen, for Aaron and his sons, and the turban of fine linen, and the caps of fine linen, and the linen undergarments of fine twined linen, and the sash of fine twined linen and of blue and purple and scarlet yarns, embroidered with needlework, as the Lord had commanded Moses.
They made the plate of the holy crown of pure gold, and wrote on it an inscription, like the engraving of a signet, “Holy to the Lord.” And they tied to it a cord of blue to fasten it on the turban above, as the Lord had commanded Moses. Exodus 39:27-31
The old testament is a foretelling of the Messiah. The priesthood of Aaron was a representation of Christ, who represented God to the people, and represented people before God. And it was to be temporary. The Messiah would come with a new covenant, and the old one would be done away.
Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin. Hebrews 4:14-15
Not only this, but since Christ is in us, we are now priests. We represent God to a fallen world, and we represent a fallen world before God as we make intercession for them.
But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. 1 Peter 3:9
Unfortunately, many believers don’t see it this way today. We have made a priesthood of our pastors, letting them represent us before God, and we hear God through them alone. We have made ourselves spectators, burying our talent in the ground, and expecting to be congratulated for remembering where to dig it up.
