Once saved always saved, true or false?

The question of "once saved, always saved" or theological concepts like "perseverance of the Saints" and "impossibility of apostasy" has been a topic of discussion among various Christian teachings. Different names are given to this belief, but they all essentially convey the idea that a Christian cannot fall from grace. However, determining the truth or falsehood of this belief ultimately relies on God's word.
To explore this, one can turn to the Scriptures. For instance, in the book of Galatians, specifically in the 5th chapter, the Apostle Paul addresses Christians who were reverting to the old law for self-justification. He warns them that such a return signifies falling from grace. This passage, among others, contributes to the evaluation of the "once saved, always saved" doctrine.
Another insightful passage is found in 1 Corinthians, chapter 9, verse 27. Here, the Apostle Paul, reflecting on his teachings and practices, emphasizes the discipline he imposes on himself. He acknowledges the need to bring his body into subjection, recognizing the possibility that even he, as a teacher, could become a castaway.
In summary, the question of whether a Christian can fall from grace is a nuanced matter, and exploring relevant passages in the Bible, such as those in Galatians and 1 Corinthians, can provide valuable insight.
We encourage all to open their Bibles, be noble, and seek the Bible's truth (Acts 17:11).
