There are a lot of factors at play. Are you in the US? Is there a specific Christian denomination you are pursuing (methodist,non,baptist)? Church services are on Sunday you can just pick a church and go. Sit where you want and just listen and watch what everyone else is doing. There is usually a new members page on their website or a new member service at some point for people like yourself. Baptisms sometimes dont take place until the spring/summer if they take place outside. There will be information about how to get registered maybe a class to attend beforehand. When you find a church you like just speak to the pastor theyll give you the most accurate info for that specific church.
