There seems to be only two possibilities: Either he isn't "willing" to end suffering, in which case he is not all-loving and therefore is not God; or, he isn't "able" to end suffering, in which case he is not all-powerful, and therefore is not God.

Why, in fact, is he the "cause" of so much, if not almost all, of the suffering mentioned in the bible? It is especially noteworthy that if one reads the bible as it is printed, without the teachings of the church, it might become apparent that the story (whether truth or fiction) is of a messiah who came to save those who had been taken captive "by" the OT God, "from" the OT God. How ironic that the caucasian community embraced the teachings and "salvation" not meant for them, and were then pulled into the belief in a God who had said he wanted nothing to do with them because they were not "His Chosen Ones".

If you have spent the night at someone's home and you have to leave in the morning, but they have not yet woken up by the time you have to leave, what is the proper etiquette for handling this?

Assume it is someone whom it would be awkward to awaken with a knock on the door. They also knew you had to leave in the morning; you aren't just running out.

Even though I'd show up at your home everyday around dinner time and acted surprised whenever you'd offer me something to eat? How long would it take you to tell me that you're on to my game and that I should eat dinner elsewhere?

Okay I have a button up shirt that is a little too long for my liking but besides that actually fits me well. So my question is should I just tuck it into my jeans. I usually dont wear shirts tucked into my jeans. Is that something that would look good on a young person (19)?

what do you think?

As a man, i can say that hearing that lots of times even from the girl i love, becomes repetitive, a ritual, and looses significance...and that if she wants to express her feelings to choose another way of doing it...remember the music?

"Saying that i love you is not the words i want to hear from you"

More Than Words.... it's all it takes...

My boyfriend and I have been dating for a long time, and we're both sexually active and practice safe sex practices. We have sex a few times a month, but sometimes I really don't want it. We'll be in bed and I'll just lie there, and he'll continue to try to get me in to it. Despite the fact I tell him I don't want to either because I'm tired or because he doesn't have a condom. I have a thyroid condition that makes my fertility rate extremely low, and sometimes I just can't get risk getting pregnant. But sometimes he'll just lift me up on top of him, or put himself on top of me and engage anyway. I don't want it.. and I seem extremely bored through the whole thing and sometimes I'll try to push him off of me, but he won't move because he's much bigger and stronger than me... and he doesn't want me to relieve his blue-balls orally, and he doesn't want to do it himself... how can I make him listen to me?
