You don't have to go to church to worship God. Going to church doesn't make you a christian. You can sit in a garage all day but it won't make you a car. And it isn't how you act every Sunday at church; it's how you act every other day of the week. I haven't gone to church in a few years to be honest, but that doesn't mean I don't pray to God. So to answer your question, you don't have to go to church to worship God. Hope I helped. Have a great week!
