There Paul says that nothing present and nothing to come can separate believers from the love of God which is in Christ. Because Paul was not addressing the subject of eternal security in Galatians, we don't find explicit statements of eternal security in the book. Nonetheless, it is telling that we don't find the opposite. The believers in the churches of Galatia were being influenced by legalistic teachers called Judaisers. These men were saying that while salvation began by faith in Christ, one could not obtain final salvation without obeying the Law of Moses.
Christians lose their grip on grace whenever they fall prey to the teachings of legalism.
If a Christian leaves a church that is clear on the Gospel and grace and joins one which is not, he will quickly lose his grip on grace if he accepts the teaching at the new church. They were to stay away. They weren't to listen to them. Conclusion Believers cease to experience God's grace whenever they attempt to be justified by the works they do. Believers who fall prey to legalistic cults and denominations are one example.
