OSAS (Once-Saved-Always-Saved) is an imprecise term that can unwittingly mislead certain people into thinking their salvation is cheaply bought and cheaply maintained. Please read my words carefully. Words mean things. I specifically wrote "can unwittingly mislead certain people", not all people. If you are mature enough in your faith to understanding what is required of you as a Christian, then praise God! However not everyone has that understanding. There is a belief in Christianity that teaches once a person has accepted Jesus as their savior they can never lose their salvation no matter what they do; even if they seemingly apostatize. This belief existed during the earliest days of the Apostolic church. Paul addressed it in Romans. There was a heretical teaching in Paul's time that taught the more a person sins the more grace God has to give them to cover their sin. Hence, continually sinning makes God look good because He is forever forgiving even deliberate sin. While it is true that every sin a Christian commits is forgiven, the idea that we should sin in order to make God look good is warped and perverted. It turns grace into something it is not, a license to sin. This warped and perverted view of grace is called Antinomianism (anti=against nomos=law, or literally against the law). Once-saved-always-saved fits perfectly into Antinomian theology. An alternate view, and one that I believe is supported by scripture, is the perseverance of the saints. Perseverance of the saints does not mean the perfection of the saints. Christians sin. They somethings commit grievous sins. In fact they may commit sins so heinous that God takes their life as an act of mercy so that they do not continue in sin (1 Cor. 11:30). Perseverance of the saints teaches that, generally speaking, Christians will give evidence through how they live their lives of actually being a Christian. This is proof (or evidence) of the transforming power of the Spirit. The reason I added the caveat "generally speaking" is because we cannot judge the unknown. We lack perfect knowledge because we are finite. A person may come to Christ and a week later and die in an accident. It would be foolish to try and evaluate their Christian walk for so short a time. I am writing from the perspective of altitude; looking at the big picture. I write this because some think that those of us who oppose the term Once-saved-always-saved means we don't believe in eternal security. It is precisely because we do believe in eternal security that we object to the term.
