If Christ died on the cross for all of humanity

No I can't!... You know a good question like this has to be answered thoroughly...a simple no I can't is not sufficient by any means...lol

 I have strong reasons why there has to be a living personal God. I know I cannot provide an argument which will convince everyone but this does not mean I don't have good reason to believe in God. In fact some of my reasons for believing in God may be persuasive to you. Even if you aren't persuaded to believe that God exists, my arguments may not be useless. Maybe some argument for God's existence will persuade you that belief in God is reasonable.

There are two basic sources of information about God. We can infer what might be true about God from what we observe in the universe. We look at the physical universe, human nature and culture and we observe things which may be clues to the existence or nature of the supernatural. God may have entered the Universe and told us true things about himself, morality, meaning and how to have a relationship with him. This is called Revelation.

Let me explain each of these. I recall the time when I was an elisted airman in the U.S. Air Force stationed at Nellis Air Base in Las Vegas Nevada. My munitions crew got a temporary duty assignment to Utopau Air Base in Thailand. We flew first to Alaska, then to Japan, then to the Phillipines, then we finally landed in Bangkok, Thailand. Let me tell you it was a very long exhausting trip lasting over 20 hours but seeing the beauty of all these places and the vastness of this earth of ours it makes sense to think that if there is some person or being who is responsible for making the physical universe, this being has a lot more power than we do. Now this is a rather simplistic example.

Another observation we can make is that every culture we know anything about has a deep sense that certain things are morally permissible and certain things are morally prohibited. This leads us to infer that if there is some supernatural being responsible for human nature, that being is personal. He has a moral aspect to His nature.

The second source of information is that God may have taken the initiative and stepped into the universe to reveal Himself. He may tell us true things about His nature and purposes and about human meaning and morality.

Christianity holds that both of these are good sources of information. We have clues to God's existence which can be observed and God has entered the physical universe through the life and teaching of Jesus of Nazareth in History and told us about himself.

Let me go into a logical aspect now. There are things which come into existence. Everything which comes into existence is caused to exist by something else. There cannot be an infinite series of past causes. Therefore, there exists a first cause which did not come into existence. In other words, the first cause always existed.

It is obvious that nothing can cause itself to come into existence. Anything that causes itself to come into existence has to exist before it exists. This is impossible. Perhaps something can come into existence from nothing without any cause whatsoever. Can a thing just pop into existence with absolutely no cause? This also does not seem reasonable.

"There cannot be an infinite series of past causes." Is the series of past causes infinite? Can the universe have an infinite past? The answer is that it cannot. First, there are philosophical reasons to think the past cannot be infinite. Second, there are scientific reasons which support this view.

I'm going to stop here and not expand on the philosophical and scientific reasons in regards to the universe not having an infinite past.

So in summary up to this point, basicly what I have said very simplistically is that if one asks "How can I know there is a God? the answer is there is the Bible, there is nature, there is man, and there is logic. These point to the Creator. None are possible by happenstance. None could have been produced by accident. "Because that which is known about God is evident within them; for God make it evident to them" (Rom. 1:19).

Finally I repeat, No I can't ever admit that there is a possiblity that God doesn't exist. I am thoroughly convinced of His existence, so He does exist...Amen!
