Thank you for your five reasons but sorry to say, all of the five I could easily contest
I'm sorry but I don't think you could.
You could look on YouTube and find a film that someone else has made and claim that that refutes the arguments - though even that is hit and miss, as sometimes the clips that you quote actually say the opposite.
But as you "can't get your head around science" I doubt that you, yourself, could refute scientific facts.
but my main reason for supporting F/E is the Bible,
Why can't you understand that the Bible does not teach the shape of the earth; it is not the purpose of the Bible to teach the shape of the earth?
No one comes to know God, trust God, be saved by God, believe in Jesus etc because of the shape of the earth.
You once said that if people believed that the earth was flat they would accept that the Bible is true and there would be conversions. There wouldn't. There are people who are convinced that the earth is flat but do not believe in God and have no intention of becoming Christians. If the FE society are out in our town, they have posters describing themselves as non religious - i.e. they do NOT say "Flat Earth teaches the truth about God", "accept the earth is flat and you will know God".
Christianity is centred in Christ. The OT prophesied that Christ would come, the Gospels described his ministry when he did come and the epistles teach us how to put our faith in Christ into practice. That is what the Bible is about; God the Father and Creator, his love for mankind and his salvation plan for his disobedient creation (us) after we chose to go our own way. We are Christians and bear Christ's name.
Believing that Flat Earth is true does not prevent someone from accepting Christ and reading the Bible.
Rejecting Flat Earth does not mean that someone has rejected the Bible - because the Bible is not about the shape of the earth.
Like Aaron said, God does not change nor will he ever.
God's unchanging nature has nothing to do with Flat Earth.
