A Call to Receive the Sign of Covenantal Inclusion

The sermon centers on the inseparable relationship between faith and obedience, illustrating how Abraham's immediate compliance with God's command to circumcise himself and his household was not a means to earn salvation but the natural fruit of his prior faith in God's promise. Rooted in the character of God—His condescension in speaking to humanity, His definitive communication through Scripture, His commanding authority, and His ascension as a promise of future judgment and redemption—obedience is portrayed as the authentic expression of a heart united with Christ. The sermon emphasizes that true obedience flows from faith, not as a legalistic requirement, but as a response to God's grace, with circumcision and baptism serving as signs pointing to the inward reality of spiritual renewal and union with Christ. It warns against the danger of external religious rituals without inward faith, citing Scripture to affirm that without faith, no one can please God, and that genuine Christian life is marked by continual pruning of dead branches and a daily pursuit of Christ as the source of strength and joy. Ultimately, believers are called to listen to God's Word with eager hearts and to obey out of love, not obligation, fixing their eyes on Jesus, the pioneer and perfecter of faith, who endured the cross for the joy set before Him.
