Probably to the same extent McArther did for his.
If I had a beef about that line of theology, it’s that it posits achieved perfection while trying to deny perfectionism. I eventually walked away from it as not being able to even pretend it could be true. I wanted to scream at MacArthur at times... well, what makes you so cocksure Jesus is your Lord in every way yet. Because you’d have to be, in order to fulfill your own theology.
The salvation promise to the yet imperfect is far more powerful. And it’s a lot less prone to arrogance.
