>>Whoever is teaching that is a liar and a deceiver. The “10 second prayer” involves accepting that one is a sinner, being remorseful for one’s sins, and accepting Christ’s free gift of salvation. Without repentance one is only muttering words. With repentance there is no “go back to your same old life”.
I think we both know that there are a LOT of people who teach that doctrine. They say, “just say this prayer and you’ll be saved, and you will be changed.” For some who say that prayer with the right attitude in their heart, it is true. But for others, it becomes a barrier to true faith because they believe that they have done all they ever need to do. If you tell them that you have to do more, they respond with “that’s just works-based salvation.”
Salvation requires transformation and that takes time and repentance. God will do the work, but you have to let him. That’s where OSAS doctrine falls flat.
I understand your point, and I agree with most of it. However, I must make it clear that salvation is instantaneous. The moment one believes and repents that person is forgiven. What you are talking about is sanctification (transformation) and yes, that takes time and repentance because, let's face it, we continue to sin. Once saved always saved, properly understood, does not negate the process of sanctification.
