He loves you and even the devil. If he would just ask to be forgiven, he would. But his pride will not let him ask for forgiveness.
Does your pride finder you also, for me it did a few years ago.
Don't answer back, just think about in your head and be honest with yourself...
You asked in your OP:
Be honest, their must be something that God could do for you, in order to believe that the earth is Flat
When I first saw that question, my first reaction was to say "Nothing could change my belief", but that's not quite true.
If God miraculously changed the earth from a Globe to flat, then I would believe.
And again He could again say
"God saw all that he had made, and it was very good. And there was evening, and there was morning--the sixth day."
And then we would see with our eyes than the earth was flat.
But, there are none so blind as those that
will not see and
there are none so deaf as those that
will not hear.
