I'd like to ask you a question, openmindedone. Do you feel any closer to having the answer to your questions? Because judging by the replies of others, if I was asking those questions, I wouldn't be.
It seems to me that half the people trying to help you are doing just that; trying...they don't actually have the answers either. Not satisfying ones anyway. The questions you ask do have an answer.
However, they aren't simple 'yes and no' answers. They require sincere effort on your part and a willingness to want to find them. Are you really prepared to do that? Are you willing to accept the reply? You are asking questions about God, why he does certain things and so on. Now, where do you think would be the best place to go, and whom do you think would be the best person to ask? Isn't best to go directly to the source? Now, there can only be one true God who can give you the answers to your very valid questions? And, believe it or not, the answers to your questions are all found, in what God claims to be his letter, his answers to us, The Bible.
Now then, if you ask a scriptural question, you should be willing to accept a scriptural answer. If you ask God a question, then you must let God give you an answer. Its only fair isnt it, otherwise you shouldn't ask in the first place, correct? Now, I have asked questions like yours myself, and guess what, I know the answers to all your questions. Do you want to know more? Then reply to this message.
Ps. just to give you something to think about as regards an afterlife, read Ecclesiastes 9:5,10 and ask yourself, if there is an afterlife or if we live on some how, we would need to be aware of what its like when we get there etc, but this scripture says that the dead know nothing, NOTHING. By the way, Sheol means the grave. But thats not the end of us when we die. (But thats another subject in itself
) If you have more questions off the back of this, dont worry, I have more answers.
