Once saved, always saved? This question is analyzed by examining all the words of Jesus and every New Testament writer dealing with both eternal security and apostasy. The eternal security passages do not conflict with the frequent warnings that believers must persevere in faith to the end of their lives to be saved, but, rather, are conditioned on the believer remaining true to Christ. Jesus and New Testament writers alike warn that, if a believer rejects faith, God gives no opportunity to once again be saved. The New Testament does not teach 'once saved, always saved,' instead, it teaches 'twice lost, always lost.'
