There are four things associated with the tabernacle that had a crown of gold. The interesting thing about the crown of gold on each of these is that they are all representations of Jesus Christ.
Ex 39:30-31, the priest that ministers to the Lord was to have a crown of pure gold on his mitre. He was to be holy. Jesus Christ is our holy high priest, Heb 7:26.
Ex 37:1-2, the ark had a crown of gold. The ark held the ten commandments which are holy, Rom 7:12. The law is holy, the commandment holy. And Jesus Christ came to fulfill the law, Matt 5:17. He is the end of the law for righteousness to every one that believeth, Rom 10:4.
Ex 37:10-12, the table of shewbread had a crown of gold. The bread on the table was holy, 1 Sam 21:6, hallowed bread. Lev 24:5-9 most holy. Jesus Christ is the bread of life which came down from heaven, Jn 6:35, 48, 51.
Ex 37:25-26 the incense altar had a crown of gold. The perfume that was burned on the incense altar was holy, Ex 30:34-37. It is most holy, it shall be unto thee holy for the Lord. Jesus Christ was an offering and a sacrifice to God for a sweet smelling savor, Eph 5:2.
And when we see Jesus in Rev 19:12 on his head were many crowns. We’re not sure what all those crowns are but you can certainly see him: Crowned as the holy high priest. Crowned as the fulfillment of the holy law. Crowned as the holy bread of life given to us. Crowned as the holy sweet smelling savor unto God.
In 1 Pet 1:15-16 he said, be ye holy, for I am holy (Lev 11:44).
To be holy we must be like Christ, by:
Fulfilling the law through his righteousness, Rom 8:4. We can’t do this without being saved and keeping the law, Rom 13:8-10. 2 Tim 2:5 “And if a man also strive for the masteries, yet is he not crowned, except he strive lawfully”.
Being the bread on earth now, (Jesus is in heaven), 1 Cor 10:17. We can’t do this without having communion with the body of Christ, 1 Cor 10:16.
Offering ourselves a sweet smelling savor to God, 2 Cor 2:14-16. We can’t do this without manifesting the savor of his knowledge in every place, both among those who are lost and those who are saved.
Being holy priests like him, 1 Pet 2:5, 9. We can’t do this without offering spiritual sacrifices and shewing forth the praises of him who hath called us. In Heb 13:15 our spiritual sacrifices are, principally, offering praise and giving thanks. This can be hard to do when you’re suffering. Paul and Silas did when they were in prison, Acts 16:25.
Those who are holy as he is holy will have crowns to cast before him in heaven, Rev 4:10, Rev 5:8-10 as kings and priests.
Conclusion: Be holy by trusting Jesus Christ to save you. Then yield to the Spirit so his righteousness can be fulfilled in you. Join with the body of Christ. Be a sweet smelling savor to God every where you are. And offer the sacrifices of praise and thanksgiving to God continually.
