He has a domain in reality and in the spiritual. And is capable of connecting those two for humans. Creation became "soiled', for keeping it a simple term, by sin. And He has overcome that as well.
Faith does have much to do with the who, how, as also the when... but that's the bridge to Him for us, right?
But first you have to believe He actually IS... or can be, for curiosity's sake, to enjoin yourself to more than the possibilities, but also the eventualities in Him. He does things with order and in order.
God is described in the Bible as both self-aware and self-existent. His self-awareness is evident in His ability to communicate, make decisions, and establish relationships with humanity, as seen throughout Scripture. For example, in Exodus 3:14, God reveals His name as "I AM," signifying His eternal and self-existent nature.
The concept of God's self-existence, also known as "aseity," means that He exists independently and is not contingent upon anything else. He is the uncaused cause of all things, eternal and self-sufficient. This doctrine underscores His unique and divine nature.
What do you think about these attributes of God?
The Bible is Psalms 14:1 - The fool says in his heart, "There is no God."
And pretty much no one here wants to be seen as a fool, correct?
In order for anything to exist, an uncaused something, or someone, must exist. It is not an uncaused effect that must exist, for there can be no such thing. Self-creation, an uncaused effect, may be an illogical contradiction, but a self-existent, “uncaused cause” is not.
This “uncaused cause” must have the power of being within itself—it must exist in and of itself. This cause must be eternal, for that which does not exist cannot later bring itself into existence. Moreover, this cause must be personal for an impersonal one could not create personal beings. Only a personal, self-existent God can answer the question: “Why is there something rather than nothing?”
