Actually I accept that the bible teaches "calvin doctrine" and equally teaches "freewill". That both doctrines coexist. Is that a problem? I mean you can read the text for yourself.
You really have to look no further than John 3:16 to know if we serve a choosy God:
"For God so loved the world that He gave His only-begotten Son, that whoever believes in Him should not perish but have everlasting life.
Yes, I more or less share your perspective. I suspect that when we find two opposite doctrines in seeming coexistence, it means that the real principle at work is more complicated than we realize...and no, I have no clue how it works, except according to the Lord's will.
"O Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing!" - Luke 13:34
