The existence of God cosmologically:The argument for cause and effect is one logical argument for the existence of God, just as everything that exists must have an aequate cause, so therefore an all-powerful being that is also intelligent is an adequate cause to explain the universe, no?
The existence of God Teleologically:The existence of God is proved by the order and the useful arrangment of the universe. the world and its orde clearly demonstrates that a great and powerful mind was behind it's arrangement.
The existence of God Anthropologically:The existence of human beings as a intelligent and moral creature is a argument for the existence of the moral and intellectual being called God.
And finally the existence of God ontologically:"BEING" is a better term for ontological and is an argument that indicates the pr5obability of the existence of God. It reason that the very idea of an infinite, perfect being cannot be derived from a finite and inperfect human being, thus, a perfect BEING who exists must have placed the idea of humankind.
With these can you still not come to the conclusion that God very well does exist?
It's sort of difficult to stay on topic, especially when one wants proof for the existence of God, anyways, if a homosexual turns away from his sins then yes, God will welcome him with open arms.
God Bless!
