Are you a golden vessel? Have you been sanctified to be used for His service?
God required the vessels of the tabernacle and the temple to be build to very precise details. Only when these vessels had been crafted to His requirements was God than able to use these instruments.
With the Ark of the Covenant, God commanded that it be built of Acacia wood and be overlain with Gold on both the Inside and the Outside. Only by building the ark to God’s specification made it possible for God to dwell in His glory on the Ark.
God has created you specifically for a purpose. When God can mold you into his purpose and make you a vessel worthy for service you can be used mightily by God.
People should be able to look at the outward appearance and know that God is living in the inside.
