David told the leaders of the Levites to appoint their brothers as singers to sing joyful songs, accompanied by musical instruments: lyres, harps and cymbals.
God's presence is holy and we cannot host His presence anyway we like. He has his "prescribed way":
- Consecration: Those who want to be carriers of God's Ark of His presence must be consecrated as prescribed in Exodus 29. This is done in four ways: (1) the washing with water, i.e. cleansing through the Word (Eph. 5:26, "washing with water through the Word"); (2) the putting on of priestly garments, i.e. the putting on the robe of righteousness of Christ by faith; (3) the applying of the blood of sacrifices on the ears, hands and feet i.e. cleansing by the Blood of Christ for sins caused by what we listen to, what we do and where we go; (4) the anointing of the garments with oil, i.e. filled with the Spirit. So, we need to daily consecrate ourselves by reading and meditating on the Word of God, putting on the robe of Christ's righteousness by faith, cleansing ourselves from sins through confession, and finally asking God to fill us with His Spirit.
- Carriers: We are to carry God's presence upon our shoulders - personally, not on carts or some other objects. The presence of God is precious and holy and can only rest on consecrated carriers. We should not be casual and careless about the Presence of God for He comes to rest on us, not the church building.
- Choirs: God delights to dwell among praising people who are rejoicing. Praise attracts His presence, but complaining and griping drive Him away. Our God is not some kind of kill-joy deity with a long beard and a long face. He delight to manifest himself among happy people who rejoice in Him. David instructed the Levites to "sing joyful songs, accompanied by musical instruments: lyres, harps and cymbals." It was a celebration of joy.
Father, You have shown us how You want us to approach You and how to welcome You into our midst. Help us make every effort to become worshipers who worship in spirit and in truth. Amen.
