Eternal Security by A W Pink and published by Baker Books.
Can every believer have assurance of salvation? Eternal security is the truth that established a Christian in assurance of salvation. There are other Biblical teachings that tell of salvation, but none of them in themselves can bring assurance to the individual soul. Eternal security completes these other teachings by showing how they apply to individuals.
When understood correctly this doctrine also safeguards the honour and integrity of God and His Word. All you are secure have been transformed by a new birth so that they become new people. This is the other half of the truth. Pink explains both - that ALL those who are born again are eternally secure, but that ONLY those who are born again are eternally secure.
