Skepticism pretty much = agnostic.
There are many who say they are atheists, but are really agnostic. There are many who say they are theists, but are really agnostic. There are those who say that if one is agnostic, one must be either an Atheistic Agnostic, or a Theistic Agnostic. But it really doesn't matter.
I am skeptical of the ability of any humans to know whether there is or is not a universal omnimax deity; I understand that you believe that there is, and others believe that there isn't. I don't hold a belief either way, except in that I doubt anyone's ability to know.
As you say, Christianity (at least can be) hard work. My experience with it was that many, even leaders in congregations, including the ministers, haven't really challenged themselves in regards to their Christianity--and they resent those who do ask the difficult questions...
And then I looked into some other religions and their sacred stories, and how their teachers and members understand those stories...and found that most hold the same certainty about their beliefs in the face of it being unlikely that any human could actually comprehend a universal omnimax deity of any sort...and that such a deity would express the positions often seen in the stories and interpretations...
But the explanation that, oh, the devil is leading you astray by feeding my doubts, or that if only I'd read the gospels with an open heart and mind I would understand...well, that's just nonsense--let's just say I see no evidence that it is true, any more than I see evidence that the religious texts and interpretations are true. If there is a God, it created me/allowed me to be born with and/or develop this Doubting Thomas comprehension of the world. If it really knows me and all about me, it knows how and why I have become the way I've become, and will deal with me accordingly. No amount of going to church will make any difference. Needless to say, I am skeptical of the fire and brimstone point of view...as well as the "there ain't no god" view, too...
