Apostle Paul goes to great lengths to clarify the gospel message. The only way a person can be justified before God is by faith in Jesus Christ. Judaizers were teaching the mosaic law and the need for circumcision for a person to become a Christian. These false brethren maintained that one had token the Jewish law in order to be saved. They refused to confess that salvation was God’s gift through faith alone. As Paul explains that would be a rejection the Good News. Salvation is God’s gift to those who believe in His Son.
