I used to attend a church when I was younger, and I went through a bit of a difficult time, resulting in me not going to church anymore.
Now that I'm older, I would like to maybe explore the faith a little more, and maybe go to church again, to find out what I, myself, believe.
I work for a business ran by a church, which is upstairs from my work, and I'm thinking of going there. A lot of my collegues go there

so that's good.
My one major concern is my sexuality. If people find out I'm gay (from one of my collegues or something), then how do I know that people won't judge me? I have no problem with being gay, in my day to day life, but I understand that being gay and religion doesn't always go together like...cheese and bread?
Do you think I should just go anyway? And if and when the time comes that people find out, then what should I do?
Of course you can go to this or almost any other church, but it won't do you any good without God's blessing upon you, and this you will not have if you are guilty of known and willful sin in your life. It doesn't make any difference if you do not recognize something which is traditionally considered as a "sin" or moral flaw, as though "sin" were relative only to your or another's opinion. Well, yes,
it is relative...It's relative
to God and not to any other inferior, moral and rational agent. If there
is a supreme Creator of all known and unknown worlds, then make up your mind here and now whether you believe in this or not as it will mean everything to you eventually. Since you do seek out some sort of Church, this would imply that you do believe in a "Creator" who is to be sought out, studied, and possibly even related to if this is even possible. Well,
it is indeed possible, but this puts you boxed into a corner that will defeat your very intention for personal satisfaction with such a mighty Being, if you are beginning at the very onset of your search for Him with something which He is definitely highly offended with. In 3 words:
It won't work, and the absence of His blessing upon you is the reason why
it won't work. What kind of a gigantic, supernatural and cognizant Being ever could or would compose our universe? Where did He get the atomic matter? A million and a half puzzling mysteries automatically confront you, and every single one of them cries out loudly and demandingly over and over one single word:
SUPREMACY. Certainly it wasn't all a ridiculous series of coincidental accidents, and if it were intelligently and designedly framed by some divine Being, then you and I and all other of His creatures had better adapt
our views into His, and not expect Him to adapt
His views into ours, as the first proposition alone is tenable while the later is utterly preposterous.
If there is a Creator to be sought out, studied and worshipped, (and there is,) then you had better adapt your views
into His, as such a profound and limitless Being
still holds the very atoms of your present construction in the very palm of His hand, and can just as easily unspeak that constitution as He can preserve it forever in felicity. It is a very wise person who fears this God.
