Sister Ann,
As you have objected by providing Psalm 150, so It is commonly objected that Psalm 150 offers instruction to praise the Lord with various kinds of musical instruments. However, these instructions are not referring to New Testament worship. Procedure used in Old Testament worship obviously cannot be used to amend the New Testament pattern; otherwise, animal sacrifices, priests, etc. could be legitimately introduced to the church. It should be observed that Psalm 150 also commands to praise the Lord with dance (Ps 150:4), yet those who use the Psalm to defend musical instruments would generally condemn dancing in the church.
What is the authority for any activities in worship? Our authority is found in three verses or passages of scripture as follows:
1. John 4:24 “God is a Spirit: and they that worship him must worship him in spirit and in truth.” 2. Mark 7:7 “Howbeit in vain do they worship me, teaching for doctrines the commandments of men.”
3. 2 Timothy 3:16-17“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, thoroughly furnished unto all good works.”
John 4:24 gives us the must of worship. Worship must be based on the truth. Anything that is not truth cannot be considered true worship. Also, Mark 7:7 tells us that there issuch a thing as vain or empty worship. That is, attempts at worship can be unacceptable to God. When anyone teaches for doctrines the commandments of men, then their worship and the worship of those who believe them will be considered vain or empty and not acceptable with God. Next, 2 Tim. 3:16-17 tell us that the scriptures provide everything that is needed for good works. True worship is a good work before God. Thus, everything that is needed for worship is provided in the scriptures. We need not go outside the scriptures to determine what we are to do inworship. Furthermore, since the scriptures thoroughly furnish us everything, if something is not in the scriptures, then it cannot be a good work. The scriptures are our authority for all activities of worship.
If the scriptures are silent, does that implicitly give authority to add anything that is not explicitly prohibited in worship the scriptures? As previously quoted 2: Timothy 3:16-16 states the scriptures are a thorough furnisher unto all good works. Thus, if it isn’t in the scriptures it cannot be considered a good work.
I will give you two examples that fully explain God’s attitude toward adding anything to what God has given in the way of worship:
1. Lev. 10:1 “And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not. 2 And there went out fire from the LORD, and devoured them, and they died before the LORD.” Obviously, God was not pleased with Nadab and Abihu, the two oldest sons of Aaron. However, we do not find anywhere in the scriptures where God ever commanded not to offer strange fire before the Lord. What we do find is that God commanded to use fire from off the altar. If silence gave implicit authority to add to what God had given, then it would have been okay for Nadab and Abihu to offer strange fire in their censers. The conclusion we draw from this is that we are to do what God commands, but we are not to add to what he commands.
2. 2 Samuel 6:3 “And they set the ark of God upon a new cart, and brought it out of the house of Abinadab that was in Gibeah: and Uzzah and Ahio, the sons of Abinadab, drave the new cart. 4 And they brought it out of the house of Abinadab which was at Gibeah, accompanying the ark of God: and Ahio went before the ark. 5 And David and all the house of Israel played before the LORD on all manner of instruments made of fir wood, even on harps, and on psalteries, and on timbrels, and on cornets, and on cymbals. 6 And when they came to Nachon's threshingfloor, Uzzah put forth his hand to the ark of God, and took hold of it; for the oxen shook it. 7 And the anger of the LORD was kindled against Uzzah; and God smote him there for his error; and there he died by the ark of God.” God never commanded not to carry the ark on a new cart, nor did he command not to steady the ark if it appeared to be shaky to fall off the cart. The problem is that God did command that the Levites were to be responsible for carrying the ark and they were to carry it by the staves through the rings on the side of the ark. Man’s hands were not to touch the ark. Even though Uzzah had good intentions, yet he greatly displeased the Lord when he put forth his hand to steady the ark.
There is no biblical precedent for the usage of musical instruments in New Testament worship. The scriptures give repeated instructions to sing in the church, but never to play (Rom 15:9, I Cor 14:15, Eph 5:19, Col 3:16, Heb 2:12, Ja 5:13).
