It has been claimed on numerous threads and in many theological circles that 'once a son always a son.' This notion is being promoted as proof of OSAS. Is it true and can such be supported by Scripture? Just because we are sons of God does not mean that a man cannot reject his faith, sin, and fall from his first estate. The physical and or legal relationship between a father and child does not directly correlate the one between God and man. The relationship that exists between God and man in salvation is one of faith based upon certain conditions being met, which in fact allows for the possibility of deception or change. The relationship that exists between a father and a child is one of necessity apart from any conditions. Would there be one on the list that would like to try and show us a verse that indicates this ‘once a son always a son’ notion from Scripture? Show us a verse that states that our relationship between ourselves as believers and God is one of necessity and not that of faith with conditions.
