True and Spiritual Worship
The church is God's chosen race, royal priesthood, holy nation, and treasured possession.
Introduction:
By stating that “we” were the true circumcision, Paul associated himself with Gentiles and Jews who relied on Christ rather than religious ritual.
The three characteristics involve worship, glory, and confidence. First, true believers worshiped by the Spirit of God. Using a term that often referred to temple service (latreuō), Paul identified inward, spiritual worship in contrast to the legalism of outward conformity to the law. The Spirit energizes and focuses Christian worship. Second, true believers glory in Christ Jesus. The term “glory” means to boast (kauchaomai), and Paul consciously contrasted the boasting of good works with boasting that is in the work of Christ. Third, true believers have no confidence in the flesh. Again he referred to a righteousness that trusts in human initiative and energy to gain spiritual blessing. Paul came to the place where he realized his own efforts were useless, and that attitude paved the way for his trust in Christ.
Physical circumcision served to identify someone with the Jewish nation and had value for purposes of ministry, but it had no value in commending someone to God. Spiritual circumcision was a matter of the heart (Col 2:11).
