1. What to say to a Mormon?
A. Refuting Mormons belief [Doctrines and Covenants Sect. 130:22] that God is material, a man with a body like us who progressed to Godhood.
God is a Spirit [John 4:24]. No man has seen God in his full manifestation and lived.
• God is a spirit that does not have flesh and bones [Luke 24:39].
• God is not a man [Hosea 11:9; Numbers 23:19; 1 Sam. 15:29].
• God is invisible [Col. 1:15; 1 Tim. 1:17; Heb. 11:27].
