Since the Bible teaches we must have the authority of Christ for whatever we practice or teach (Colossians 3:17), our worship services will be conducted strictly in accordance with the Scriptural patterns set forth in the New Testament.  Jesus said, "They that worship [God] must worship Him in spirit and in truth" (John 4:24). 

To worship God "in spirit" means to worship Him with the right attitude and motives.  In other words, the condition of the heart must be acceptable in our worship.  To worship God "in truth" means to worship Him according to the Word of God, for Jesus said that the Word of God was truth (John 17:17). In other words, all that we do in worship to our God must be regulated by the truth, which is the Word of God.  Jesus said that the truth was knowable (John 8:32), but we must be willing to diligently study God's Word to find it (2 Timothy 2:15, Acts 17:11, Matthew 7:7-8). 

We must also be willing to receive the truth with meekness (James 1:21).  Indeed, Jesus expects us to understand and follow the truth, for He promises indignation, wrath, tribulation, anguish, a fiery vengeance, and everlasting destruction for those who do not obey the truth

(Romans 2:8-9, 2 Thessalonians 1:8-9).
