He wants you to ask him because he is your FATHER. But sometimes a FATHER tells his child "no" for many, many reasons that aren't apparent at the time. We still love our earthly father's even when we don't get what we ask for, don't we?
Think of a relationship between you and your OWN father. Your Father most likely knew what you wanted, but waited for you ask. Same thing.
BTW, faith is believing in something even if you can't see it. It's not complicated.
Trying not be be onerous, but in my agnostic role:
How can I know if He’s my Father? Why would a good father hide himself totally from his children, create them in a fallen state, and then punish them for being fallen?
