That is not his meaning as all do not see themselves as sinner and Jesus did not come to save the righteous but sinners only. Only the elective grace of God makes sinners see themselves as sinners and until you can see that there is no need for salvation. Until you can see you are "lost" there is no salvation needed for those who see themselves as "just" and as a son who "never sinned at any time" against the Father.
Oh brother! Don't you Calvinists ever get tired of saying scripture doesn't mean what it plainly says?
Doesn't that kind of throw up red flags all over the place?
If I went to church and my preacher kept telling me scripture doesn't mean what it says, I would get up and walk out quick.
