Point the 1st: We have faith, not knowledge. Indwelling knowledge is Gnosticism; Jesus taught faith.
We have both, and faith is not blind. Is your position that you know nothing of God? Or, is your position that you do not know God personally? BTW, how can Jesus or anyone else teach anything without knowledge being involved?
Point the 2nd: Gentiles CAN be saved; there is no guarantee.
Yes, absolutely true. I meant that we know that SOME are saved.
Knowing of something is not knowing it. You may have heard of something, and you know that it exists, but you have no clue what it is.
Knowing God personally is a different story. Those who claim they know God personally open up a can of worms with such claims. Have you seen Him? If so, how do you know it was God? Have you heard Him? The same question follows.
Then there is a problem of credibility of such personal experiences. When challenged, the usual answer is "I swear I have" as "proof." Making such extraordinary claims without extraordinary evidence or proof is foolish, self-serving and self-cenetered, and most of all not convincing.
FK: Yes, absolutely true. I meant that we know that SOME are saved
No we don't. We only know that we can be, and hope that we will be. Those who are dead know. We can only hope.
