In David Green's sermon on Galatians 3:3, he addresses the issue of legalism within the context of sanctification among sovereign grace Baptists. He highlights the danger of transforming sanctification into a works-driven practice, where additional rules and regulations overshadow the true essence of faith, which should be led by the Spirit. The sermon critiques the tendency of some churches to impose numerous rules for membership, akin to the legalism criticized by Paul. Green emphasizes that Christians are born spiritually, not naturally, and maintaining faith cannot rely on the flesh but must be guided by the Spirit.

But very seldom do we hear of anybody preaching a works-based salvation among sovereign grace Baptists. But where we sometimes see people going legalistic is in sanctification. And the question comes right here in verse 3. Are you so foolish, having begun by the Spirit, are you now being perfected by the flesh? Some men will take sanctification and They'll run with it in a legalistic way and preach rule after rule after rule until it becomes such a works-driven religion real quick.

And indeed, some churches will add to and say, alright, you've got to do this, this, and this, and this, and this in order to be or remain a member of this church. Sunday after Sunday after Sunday, the sermons are all about, you've got to do this, you've got to do that, and you've got to do this. On and on we go. And I mean even to the point of it's no different than what was happening here. Let us remember, we did not become Christians by natural birth, but through spiritual birth.

The flesh will not keep us in the faith. And if we focus on the outward, the works of the flesh, we have missed the point.
