>>Once saved always saved, properly understood, does not negate the process of sanctification.
What about the person who goes to a revival, and repents with every ounce of his being at the altar call and says the sinner’s prayer. Then, a couple days later, it wears off and he returns to his life of sin.
There has to be some transformation at the moment of justification, or the person will never begin the path to sanctification.
I think that the problem is the point that we define as our moment of justification. A person could reach that point without ever uttering a special prayer. And another person could try it 1000 times without ever having that transforming moment that enables him to begin walking towards sanctification.
Just look at John Wesley. He was a priest for years before he reached the point of justification and then he spent the rest of his life working towards Christian perfection.
The issue is how do you know he"repents with every ounce of his being"? But let's assume that he does. I agree, there is a transformation because if he really repents and believes he is then indwelt by the Holy Spirit. Can he return to his life or sin? Sadly it happens sometimes, but it doesn't last. The Holy Spirit won't allow him to forget that he is a son living in a pigpen!
