A higher power represents an Unknown God, which was addressed by Paul to the Philosphers in Athens in the Book of Acts Chapter 17. Even to this day, people prefer an Unknown God rather than the True and Living God because it costs them nothing and requires nothing of them such as Obedience, Purity, Honesty, Truth, Faith, etc.
The late Prophet Art Katz stated it well in his book “Apostolic Foundations” (I’m paraphrasing) Men love to speak about a higher power because it sounds so spiritual, but will we congratulate them for that kind of spirituality, or will we see how deceitful such a statement is? There is something in the human heart, which likes to keep God at a great distance. The human heart wants an impersonal God, because an impersonal God doesn’t say, “Thou shall not commit adultery” or “Thou shall love the Lord Thy God with all your heart”.
