The Jewish audience. Paul confirms this in Romans where he speaks of a remnant saved by grace.
No, it's simply ignorance. No one believes correctly about everything.
Not if they have faith. They are saved.
One either has faith or not. You cannot be in belief and unbelief at the same time.

God draws through people at times. He employs human agency, but the individual isn't drawing, but God. There is no power in an individual to draw. God often uses circumstances to draw people. Do the circumstances have the power to draw?
People don't draw, God does. There is no power in people to draw. The power is of God and it is meant to be understood that way...2 Corinthians 4:7-10. People aren't drawing. God is.
Faith comes by hearing, and hearing by the word of God. We do believe as a result of God employing His Spirit and word. Are you the Spirit? Are you the word of God? Then you didn't cause your belief; God did. That's the issue. Certainly the cross is an act of love and grace. But the grace...

Yes, using people. We have this treasure in earthen vessels so that the power is credited to God...2 Corinthians 4:7-10. People are used. The power is of God.
Plant a branch and see how much fruit you get. Jesus said you can do nothing apart from Him.
