We should focus on Christ, It doesn't matter whether the earth is flat or not.
Titus 3:9
But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless.

It's good to talk about end times prophesies but it shouldn't consume all that you talk about because God is going to judge us on our hearts and we need to get into scripture that will grow our character, not saying that revelations cannot grow ones character but it shouldnt be as heavily dwelt upon. God is going to save who he is going to save no matter what, It doesn't matter if you were introduced to God via flat earth ideologies or not. God loves you, And I am not condemning you but these ideologies lead to things like the mandela effect, and some believers of that think the bible is entirely unreliable due to dimensional defects.. Just Hold to the gospel and do not follow pointless controversies.

that is my view point
