I need some help religiously every now and then I doubt if god exists are their any ways to overcome this I don't want to doubt like this im?

We need to always trust and believe God. There are times when most every will have a doubt. Just pray and ask God to help with your unbelief. Read the New Testament every day.

Have you read Exodus, Leviticus, Deuteronomy and Numbers?

It's about the children of Israel and how, no matter what God did, they always doubted him with whatever came up next. It's like God was only good to them after they overcame some problem that arose. It's as though God wasn't important to them, and whatever he said, it was treated as some cheap trinket.

I hope you don't treat God as something cheap, and only worthwhile when he just got you out of something. The children of Israel behaved badly, but so have I, and apparently that's what you are doing right now.

never doubt always trust god
