God gave us the Bible to serve as our final authority in all matters of faith and practice. This certainly includes the types of songs that should be sung. In fact, the Bible contains an entire book of songs, the Book of Psalms. According to Colossians 3:16, the psalms is only one of three categories of songs to be sung by New Testament believers. Basically, psalms are scriptures set to musick, hymns are doctrinal songs speaking specifically of the Lord, and spiritual songs deal with the Christian life and practice. A diligent study of history yields evidence that God’s people have been singing songs from each of these categories since the church’s inception.
The New Testament frequently incorporates minor word variations when quoting Old Testament passages. Some Bible critics have pointed to these variations suggesting that the Bible contains contradictions. However, Bible-believing students know that these variations actually provide additional light and understanding of God’s word. For example, Romans 3:13 quotes Psalm 5:9 with the variation in wording shedding light on the meaning of the word flattery. The phrase from Psalms reads “they flatter with their tongue” (Psalm 5:9). Romans modifies this Old Testament quotation by stating that “with their tongues they have used deceit” (Romans 3:13). This indicates that flattery involves the use of deceitful words; and according to 1 Thessalonians 2:5, the motive is often connected to covetousness.
