Ross's sermon on Freedom in Christ: Galatians 4:8-5:1 calls us to stand firm in the gospel, rejecting any attempt to earn salvation through works. He emphasizes Paul's warning to the Galatians, who were turning back to legalism and idolatry instead of embracing the freedom found in Christ. Paul reminds them that salvation comes by faith alone, not by obeying the law. Using the story of Abraham, Ross illustrates the contrast between trying to take control and relying on God's promise. His message is clear: we must let go of idols, relinquish control, and cling to Jesus, standing firm in the freedom He has secured for us.
