What is God? If you don't have a fairly clear answer to this question, then I have one additional question for you. How can you claim to worship something you can't define and don't particularly understand? What does it look like to worship such a thing? More importantly, if you aren't sure what this god is, how is worshiping it any different from worshiping nothing at all?
What is God? Is it an idea you've derived from one of the many versions of the Christian bible? Since these bibles were written by men, how can you be so sure that the idea they describe is accurate? What leads you to think that their understanding of God was any better than yours would have been had you not read their words? You may have noticed that the god described in the Old Testament is fairly different from the one mentioned in the New Testament. Which is the correct god, and how do you know?
What is God? Is it an idea you have been taught by your family, friends, church, and culture? You may have noticed that there is great variability in what people around you believe about God. Who is right, and how do you know? What if you've been worshiping the wrong god all this time?
What is God? Perhaps what you are worshiping is your own unique understanding of God based on everything you've been taught, your personal experiences, and how you've interpreted them. This would certainly make sense and is probably how most religious people understand God. But how is this meaningfully different from worshiping yourself? Wouldn't this mean that worship is really a form of self-love?
What is God? And if you aren't sure, are you only claiming to believe in it because you have been told that you are supposed to do so? Perhaps your faith has been misplaced. You just might be an atheist in hiding.
