Just because someone observes an outward religious ceremony doesn't mean they are in a right relationship with God. In this sermon, R.C. Sproul explores Paul’s warning in Romans 2 to the Hebrews who considered circumcision as proof of their citizenship in God’s kingdom. God looks beyond outward appearances and examines the heart.
