John Nelson Darby emphasizes the distinction between the law and the promise in his sermon on Galatians 3, explaining that while the Galatians were Christians, they mistakenly mixed the law with the gospel. He highlights that true peace comes from faith in Christ's completed work rather than from adherence to the law or ordinances. Darby asserts that believers are not under the law but are blessed through faith, as exemplified by Abraham, and that the law serves to reveal sin rather than provide salvation. He concludes that redemption is accomplished through Christ, who bore the curse of the law, allowing believers to receive the Spirit and the blessings of faith. The sermon calls for a complete reliance on Christ for righteousness and peace, rather than self-effort or legalism.

Major Ian Thomas emphasizes that the law was unable to provide salvation, as it merely highlighted humanity's sinfulness and need for redemption. He explains that God's covenant with Abraham foreshadowed the coming of Christ, who fulfilled the law's requirements through His sacrificial death and resurrection. The sermon illustrates that salvation is not about adhering to the law but about receiving the life of Christ through faith, which brings about regeneration and a new relationship with God. Thomas encourages believers to rely on the Holy Spirit for strength and guidance, rather than attempting to achieve righteousness through their own efforts.
