One Gospel, One Foundation: Discussion Guide
Sermon Video
Summary
In Galatians 2:1-10, the Apostle Paul addresses a critical question: if his gospel came independently from Christ and not from the Jerusalem apostles, could it be a different gospel altogether? Paul travels to Jerusalem, lays his gospel before the influential apostles, and the result is a resounding confirmation of unity. The Jerusalem apostles added nothing to Paul's gospel, required nothing of Titus, and extended the right hand of fellowship, proving that there is one gospel, one foundation, and one Lord building His church upon it. The sermon draws out three movements in the text: Paul's consultation with the Jerusalem apostles to test the foundation, his confrontation of false brothers who had infiltrated the church to rob believers of their freedom in Christ, and the final confirmation that Paul's gospel and the apostles' gospel are one and the same. Pastor Mike applies this to the present day by calling the church to know the gospel deeply, guard it through membership, partner wisely, and honor leaders without placing them above Scripture. The foundation stood unified in Paul's day, and because everything depends on it, the church must continue to preserve it today.
Intro Prayer
Heavenly Father, thank You for bringing us together around Your Word today. As we open Galatians 2 and discuss the one true gospel, we ask that You would quiet our hearts and open our minds. Remove any distractions or preconceived ideas that might keep us from hearing what You want to say to us. Give us a deeper love for the gospel of grace, a clearer understanding of why it must be preserved, and a willingness to apply what we learn to our own lives. May this time together draw us closer to You and to one another. In Jesus' name, Amen.

Questions
Paul says he went to Jerusalem 'because of a revelation' rather than because he was summoned. What does this tell us about the source of Paul's authority and the nature of his relationship with the Jerusalem apostles?
Pastor Mike compared Paul's visit to Jerusalem to a building inspector checking the foundation. Why is the unity of the apostolic gospel so foundational, and what would have been at stake if Paul and the Jerusalem apostles had been preaching different gospels?
Paul brought Titus, an uncircumcised Greek believer, to Jerusalem as a kind of living test case. What did the apostles' response to Titus reveal about the true gospel, and why did that action speak louder than words?
Pastor Mike described false teachers as wolves in sheep's clothing who know how to say all the right words. How can a deep knowledge of the true gospel protect us from being deceived, and what does that kind of deep knowledge look like practically?
Paul says they 'did not yield in submission even for a moment' so that the truth of the gospel might be preserved. Can you think of a time when standing firm on a conviction came at a personal cost? What gave you the strength to hold the line?
Pastor Mike said that whenever we add anything to the gospel, we lose everything rather than gain anything. What are some things people today are tempted to add to the gospel of grace, even with good intentions?
The sermon drew a distinction between a confused sheep who receives correction with humility and a wolf who digs in. How should that distinction shape the way we respond to people who seem to be teaching something contrary to the gospel?
Pastor Mike closed by asking what foundation each person is personally standing on before God. What are some of the 'balsa wood foundations' people trust in, and how does the gospel of grace alone through faith alone in Christ alone differ from all of them?
Life Application
This week, take time to write down in your own words what the gospel is, as if you were explaining it to someone who had never heard it before. Then ask yourself honestly: is there anything you have been quietly adding to the gospel, whether in your own sense of standing before God or in how you present the faith to others? Bring what you find back to Scripture and let the truth of grace alone, through faith alone, in Christ alone be the firm ground you stand on every single day.
Key Takeaways
The gospel Paul preached and the gospel the Jerusalem apostles preached are one and the same, confirming that there is one unified gospel foundation for the entire church.
The best defense against a false gospel is not a list of things to avoid but a deep, settled, and joyful knowledge of the one true gospel, studied so thoroughly that counterfeits are immediately recognizable.
False teachers often come from within the church, looking and sounding like believers, which means the church must be watchful without being paranoid, correcting confused sheep gently while holding the line firmly against wolves.
Gospel preservation is not mean-spirited gatekeeping but the most loving act the church can perform, because adding anything to the gospel robs people of their freedom in Christ and clouds their access to saving grace.
No human authority, whether a pastor, a council, or a denomination, stands over the gospel to validate it. The gospel itself is the highest authority, and every leader must stand under it rather than over it.
Ending Prayer
Father, we are grateful for the one gospel, the good news that we are saved by grace alone, through faith alone, in Christ alone. Thank You that this foundation cannot be cracked by any scheme of man or power of darkness. As we leave this time together, help us to treasure this gospel so deeply that we are naturally protected from anything that would distort or add to it. Give us courage to hold the line when it is costly, compassion to correct those who are confused, and humility to always place ourselves under Your Word rather than over it. For anyone in this group still searching for solid ground, draw them to the finished work of Jesus Christ, the only foundation that will hold. We ask all of this in the name of Jesus, our cornerstone and our only hope. Amen.
