What does the Bible say about worshipping God in the Spirit?

The Apostle Paul in Philippians 3:3 describes those who are 'the circumcision' as those who worship God in the Spirit. This worship is contrasted with mere formalities and fleshly worship. True worship arises from a heart that has been spiritually circumcised, recognizing its lost condition before a holy God. It involves a genuine expression of reverence and adoration, driven by the movement of the Holy Spirit within us. Thus, worshipping God in Spirit means engaging with Him authentically, acknowledging our dependence on His mercy and grace while glorifying Him for His work in our lives.
