QUESTION: May Christians today look to the Old Testament for authorization to use instruments of music in worship to God?
ANSWER: No! Those who have lived, are living, and will live from the cross of Christ until the end of time are to be judged only by the New Testament of Jesus Christ (John 12:48).
The Old Testament has been taken out of the way and replaced by the New Testament. Please read carefully the following passages: Romans 7:4-7; II Corinthians 3:13-14; Galatians 3:24-25; Ephesians 2:13-16; Hebrews 7:12; 8:7.
In Colossians 2:14, we see that the handwriting of ordinances (Old Testament) was blotted out; that it was against us; that it was contrary to us. Therefore, He took it out of the way, nailing it to His cross! Because of this, Christians cannot look to the Old Testament for authority to offer animal sacrifices, burn incense or worship with mechanical instruments. More important, there is no authority in the New Testament for us to engage in any such acts today. To do so is to sin and fall from grace (Galatians 5:4).
The New Testament, by which we will be judged, authorizes only congregational, vocal music (Ephesians 5:19; Colossians 3:16-17).
