This sermon explores the pivotal moment in Acts 15 when the early church grappled with the question of what makes someone a Christian. It delves into the tension between adherence to Old Testament laws and the new covenant of grace through Jesus Christ. Pastor Jeff emphasizes that salvation comes through faith alone, not by works or adherence to ceremonial laws. He explains the historical and spiritual significance of circumcision and how it relates to Christ's sacrifice, ultimately pointing to the sufficiency of God's grace for salvation.
