Eternal Security: Once Saved, Always Saved?
Some modern-day Christians have been taught to believe in the doctrine known as “eternal security” (commonly known as “once saved, always saved”). But is this belief scriptural? Let’s allow the scriptures to speak for themselves.

“I mention it that you may be saved” (John 5:34 NIV). Notice Jesus says, “you may be saved”, not ‘you are saved, case closed, period’, as some would have us believe”. Salvation is not guaranteed to everyone, or anyone. See Matthew 7:21-23.
