Your equivocating the word question. In the sense you originally used it, it means to doubt. If you doubt something you are taking a position.
It's fine, doubt is a good thing. I don't know why you wouldn't want to provide an argument for some claim you doubted.
The point is that I dont have to take a position, e.g. of doubt, to question an asserted belief. See the argument Ive given below. (I also question things that Im broadly in agreement with.) But inescapably the onus is on the one making the assertion for supernatural beings to demonstrate the truth of what is claimed.
However if you just want to ask questions most religious folks will provide plenty of answers.
Debate generally is about questions and answers, which elicit a discussion. Religious belief is propositional and, as with any argument, having made the claim the theist must now defend it (the burden of proof).
A theist states: God is love
.
So the sceptic asks:
But how can God be love when there is so much pain and suffering in the world?
Theist: God gave us free will; we have the choice to receive his love or reject it.
Sceptic: In that case he cannot be a God of Love but only a God who sometimes loves, sometimes not.
Theist: God is always loving even when we sin and turn against him
Sceptic: But he punishes man with pain and suffering
Theist: Man punishes himself
Sceptic: But God allows suffering. So how can he be All Loving?
Theist: Trust in God. You must open your heart and believe in order to understand
Sceptic: But with what youve said above God cannot exist!
Theist: And yet you cannot prove that he does not!
The theist has now passed the burden of proof to the sceptic with an argument from ignorance.
