The incorrect and unbiblical idea that although God created the universe He no longer has any ongoing involvement with it. Conversely, Christianity believes He is vitally involved in the affairs of humanity, as displayed by providing the means of salvation and His continuing work in the lives of His followers.
While there are many things we do not comprehend, God does exist and is very active in the world. Everything that takes place is subject to His sovereignty and authority to bring about the divine plan. "My purpose will stand, and I will do all that I please...What I have said, that will I bring about; what I have planned, that will I do" (Isa 46:10,11). A deistic view of God is simply a failure in attempting to explain the unexplainable, it is relying solely on human reasoning.
