what does the bible say?
The entire Bible is God's Word and contains a unified message, so worship in the Old and New Testaments, though outwardly different, has the same foundation. Old Testament Mosaic Law presented required worship rituals, including animal sacrifice, which is not part of Christian worship because Jesus was the ultimate sacrifice for our sins (John 1:29). But underlying Old Testament worship was the core commandment to love God with all one’s heart, soul, and strength (Deuteronomy 6:5), which Jesus later described as the “great and first” commandment (Matthew 22:36–40; Mark 12:28–34). That commandment is still at the core of all worship. But the particulars of Christian worship are largely based on the teachings and principles contained in the New Testament. True worship is in spirit and in truth (John 4:23–24), a lifestyle response to God, not just something done through music at church (1 Corinthians 10:31). Christian worship is also not merely individual, but communal (Acts 2:46–47; Hebrews 10:25). It can involve many different acts of reverence—singing, praying, and more (Acts 4:31; 16:25; 1 Thessalonians 5:16–18). Christian worship puts the focus on God, rather than self (Romans 12:1).
