Worship was not man’s idea, but God’s. Therefore, He alone is in a position to determine how He is to be worshiped. The first four of the Ten Commandments can be seen as instruction regarding worship: (1) Worship God only. (2) Do not worship God using idols. (3) Do not worship God thoughtlessly (in vain). (4) The Sabbath is to be set aside as a special day for worship.[1]
In Deuteronomy 12, God instructed His people to worship Him only according to His instructions, expressly forbidding them to worship Him: (a) according to our ideas and desires (v.8), and (b) in any manner in which pagans worship their gods (v.30). The principle for worship here is no less applicable to the New Testament Church than it was to Old Testament Israel. We must search the scriptures to learn how God wants to be worshiped, rather than copy the ways of the world or try to come up with new and innovative ways to worship God. The only right ways to worship God are biblical ways.[2]
What are the biblical ways to worship God? (This is not an exhaustive list.)
Singing. Singing has always been and will ever be an integral part of worship. This is true not because music moves the heart and emotions (which it certainly can do), but because God has ordained music for worship. The reason music moves the heart and emotions is because God ordained it to be so. If anyone might doubt the place of singing in biblical worship, he has only to look at the book of Psalms, which is the Bible’s hymnal, and the largest book in the Bible. Some have argued that vocal music is appropriate for worship while instrumental music is not. While it is true that there is no instrument like the human voice with which to praise God, prohibiting musical instruments would require editing the Psalms to erase the numerous times instruments are mentioned and even commanded (e.g., Psalm 150).
The Lord’s Supper. This special remembrance of Christ’s sacrificial death was instituted by Christ Himself (Matthew 26:26-28). The Apostle Paul instructed the Church to observe the Lord’s Supper with all due reverence (1 Corinthians 11:17-34).
The Church is not unified regarding some of the particulars of how to receive communion or how often. Differences arise over whether to use wine or unfermented juice, and leavened or unleavened bread. Some observe the sacrament weekly, some monthly, or even less frequently. What is right regarding these and similar questions appears to be left to conscience. What is not allowed is using elements that have no relationship to bread and wine, downplaying the importance of the Supper by partaking with a lack of reverence, or a failure to observe the Supper with some measure of regularity and frequency.
Sacrificial Worship. Old Testament sacrifices were the central means of worship. While we do not offer the ceremonial sacrifices of the Old Testament—because Jesus’ sacrifice on the cross is the once-for-all sacrifice for sin—we are to offer “the sacrifice of praise” (Hebrews 13:15). This includes worshiping God in song when we do not feel like it, giving attention to the reading and preaching of the Word of God, giving our money sacrificially, and giving our time sacrificially. The most important thing we can give the Lord as an act of worship is ourselves, including our bodies, which is our “reasonable act of worship” (Romans 12:1).
Notes:
[1] The Fourth Commandment not only commands us to cease from our normal labors, but to worship!
[2] Obviously the particulars of Old Testament temple worship (sacrifices, etc.) are obsolete as revealed in Scripture. (See Hebrews 7-10.)
