Honestly I’m not sure what I believe yet. I think that life is about finding yourself and a region and a way of life that is one with who you are and what you believe. Not following a religion blindly and that becomes what you believe.
But these are my thoughts on the subject (I hope it helps and I hope you do well on your speech)
I don’t think that God let’s bad things happen to us, I know that God loves everyone. He made us in his image, he wants us to love each other, he wants us to be to happy with the way he made us. But I think it’s the people who ignorantly follow the words of a book written hundreds of years ago by mortal hands, are to blame. God gave us free will and that gift is also a curse. He can’t stop what people do, but he can make sure that those people don’t belong in heaven. The people who pick and choose what to follow from the bible, then continue to use the bible as a weapon as they see fit is not Christian. God said that he will judge us, if you live a good life then whether you are gay, straight, bi, lesbian, trans, you will get the happy afterlife you deserve.
