Let's have a look at all this.

God doesn't reveal things to you because you're not His. Never have been.

You can't possibly know any of this. It's also factually untrue.

Christ has already returned as promised (do you deny that Christ has come in the flesh?) through His chosen vessels. You missed the memo, son. Its an exclusive "club" by election only and you ain't in it.

I don't know what religion you follow, but it's not Christianity.

Darkness. Complete and utter darkness surrounds you. Unfortunately, you'll never be free of your own delusion until you perish.

This is a curse. I reject it utterly and reflect it back to you. What sort of person utters curses these days? Hmm?

Welcome to the great and terrible day.

The Great and Terrible Day (of the Lord) will come at His choosing, not at your utterance. If you're a human soul, return to Christ and receive forgiveness, otherwise never mind as it's already over for you.
