What if you’re worshipping the wrong god?

I would answer: "Let's examine the evidence to see if I'm right or wrong."

A Christian would answer: "I have faith that I'm right. No evidence is necessary. I believe what I believe regardless of the scientific evidence." This is what prompts the question, "What if you're wrong?"

Beliefs are flimsy and can easily be wrong. Evidence is solid, as long as we seek the best evidence and make well-reasoned conclusions based on it.

Wouldn't change the way I live my life. Then ask them what they would do differently day-to-day if there was no God.

That question is overly broad. But assuming the question is of the existance of a god, any god, my answer is also why I am an agnostic atheist. If the power that runs the cosmos actually has any sort of unified consciousness(of which I see no convincing evidence), then either it does not give a shit about us individually, in which case it matters not what we believe, or if by some stretch of the imagination it gives a shit about us individually, then Abrahamic religions' notion of an all powerful, all knowing and infinately loving god that happens also to be wrathful is an oxymoronic impossibility. The Christian paradigm--my cultural point of religious reference--contradicts itself on this score and thereby disproves itself. Either god forgives his ignorant creations for being as he created us, or he is not a loving God. All I can possibly do either way is to follow my conscience. Disbelief is NOT rebelliousness for which to be punished. It is instead ACTUAL honesty, which is supposedly a virtue for Christians.

Wrong about what? Not knowing? Uh, guilty. Sorry.

I was wrong about Santa for the longest time. I think I was seven before I figured it out.

I'm not wrong. I'm Agnostic lol

If someone was wrong though, God should show mercy and understanding because God would have been the one to make the non-believer the way he or she is. If God is all knowing and creates and shapes us the way we are then God knows the outcome already. So why would that God be so "evil" as to deny a non-believer eternal happiness? God, you done fucked up!

If there were a God, he would certainly care enough to give us his words, proven to be original, without error or inconsistency, and unnecessary of human interpretation.

He didn't!
