If we have no free will to respond to the grace of God and all is predetermined by God’s election, then why do you even bother to convince anyone of what you believe is the truth? After all, if I do not have free will what I believe or do not believe is not my choice and has been predetermined by God.

Is it troubling that the God of the universe, transcendent and sovereign, high and lifted up, Holy, Holy, Holy can manage your mind as well as the 10 to the 67987789666 molecules in our bodies?

Of course you have no free will, if by that you mean you function independent of God. If you mean that you must be able to "feel" His control of your mind and your behavior or it does not exist, then you are simply mistaken. Proverbs 21:1, "The king's heart is like a channel of water in the hand of the Lord. He turns it wherever He wishes." What kind of believers are we? This kind of persuasive description of God is throughout the Scriptures.
Romans 9:19. Paul clearly recognized that it would be troubling to hear that you are held guilty when you are held captive by His will. His answer? Too bad that this bothers you, but God is able to do whatever He wishes and He is not unjust in doing so. This is precisely why the man-made religion of Rome is not biblical. Notice the semi-pelagian argument coming out of the woodwork, now.
Because they believe that they are an elite Brahmin caste and they like to sneer -- completely unChristian...
