The problem I have with this is that, everything material ages. Time goes on. Nothing lasts for ever, not even the strongest materials we know of, eg. Diamond will last forever; thus everything has an end, and most therefore a beggining, because to suggest that an ending exists, one must have also started in order to reach that end.
I'm not sure if it is true that one needs a beginning to have an end (maybe it one does), but since I believe the Universe had a beginning this is an ok assumption of most physical things.
The only way anything could be eternal is if something immaterial were to exist, which is a common suggestion of Substance Dualism. The problem with this theory is that if God were real, and were eternal, it must be immaterial.
What does immaterial mean? Later on in the post you seem to assume 'immaterial' is a type of substance that can only interact with other immaterial substances.
If you mean to say God is a substance than I would disagree. God can be conceived of as simply the basic foundational existence of reality. God isn't any 'thing' but rather the foundation of everything. This is not pantheism but panentheism.
(This is my understanding of God before my loss of faith).
The laws of logic and science dictate that for anything to interact it must share similar properties.
I agree that that is true in science, but what law of logic dictates this?
I think the important thing to note here is the definition of 'interact'. I am pretty sure the common understanding of that word doesn't apply to God.
Also note that I am not a theist, I am simply arguing against you because I think your argument is incorrect.
When a billiard ball strikes another, it transfers kenetic energy, because both balls have a mass, velocity (0 if stationary, but still a velocity) and other physical properties. If God were real and therefore immaterial, he would not be able to create or influence anything within the material world.
The problem with this is that it assumes God is a substance separate from the material. If God holds all things in existence at all times then God is connected to all things at all times. In some sense all things are part of God.
The bible teaches that God is omnipotent, so would be able to interact with the world. The only ways out of this is to suggest one of 3 things. 1. God is material, yet real, and therefore is not eternal, and cannot be omnipotent. 2. God is real, yet immaterial, and therefore not omnipotent as he cannot influence anything in the universe that is material. 3.God is not real, because the concept of omnipotence and omniscience defy anything logical.
4. Everything is in God, but God is also more than merely the universe. God can influence the universe in that He can influence Himself/ the basic existence of all things.
These is the primary reason I lost my faith.
Well in my opinion it isn't a good reason, but there are good reasons to doubt. I hope you don't mind my criticism.
Please don't take offense (none is intended), but being raised in a Christian family does not make you a Christian. So it's quite possible that you didn't have any "faith" to lose.
True, but that doesn't mean that every teenager who loses faith never was a Christian to begin with. Not to sound big headed, but if I was never a Christian in my teenage years then no teenager is a Christian.
