And it was the duty of the trumpeters and singers to make themselves heard in unison in praise and thanksgiving to the Lord, and when the song was raised, with trumpets and cymbals and other musical instruments, in praise to the Lord, "For he is good, for his steadfast love endures forever," the house, the house of the LORD, was filled with a cloud, so that the priests could not stand to minister because of the cloud, for the glory of the LORD filled the house of God.
(2 Chron. 5:13-14)(ESV)
Scripture assures us that God notices and responds when we worship Him. That worship may be as formal and elaborate as the ceremony to dedicate the temple (2 Chr. 5:11-14), or it may be as simple and spontaneous as the worship of the early church, which often met in people's homes (Acts 2:42, 46-47). What matters most is not the setting or the program so much as the content of the worship and the heart attitude of the worshipers (Jn. 4:21-24).
It is interesting to compare the account of the temple's dedication in 2 Chr. 5-7 with the account in 1 Kg. 8. Second Chronicles provides less detail until it comes to the singers and trumpeters. Then it shows how the musicians' harmony in pitch and purpose brought the ceremony to its climax (2 Chr. 5:13), and how God responded by blessing the occasion and the temple itself with His glory and presence (2 Chr. 5:14).
The New Testament makes no mention of early Christians engaging in anything like the carefully scripted and rehearsed ritual that the Hebrews practiced. Nevertheless, God responded to the Christians' worship with similar assurances of His presence and power (for example, Acts 4:31).
So we are encouraged to worship the Lord in whatever ways are appropriate to the circumstance. He invites us to "come before His presence with singing" (Ps. 100:2)---whether that means painstakingly detailed ceremonies led by professional singers and musicians, or simple prayers and songs of heartfelt praise. Either way, He longs for us to "enter into His gates with thanksgiving, and into His courts with praise" (Ps. 100:4).
