Interesting article! The term 'radiance' is spot on. Did the face of Moses radiate after neing in God's Presence? The spacetime implications of energy source are iof great interest to me since I am convinced there are spatio-temporal variable coordinates we cannot perceive currently, that exist as real as sunshice. Some of those coordinate limits will available to us when Jesus returns in the first Heaven to collect His Body of Christ and return to the Father's House. Why do I say that? Because John wrote that when He appears we shall see Him as He really is now in His glorified body, for we shall be LIKE HIM in that expanded coordinate state.
There are lots of examples of those coordinate states scattered throughout the Bible, Old and New Testament.
Is the Shroud the real burial wrapping of Jesus my Lord? I cannot prove it but I believe it, even as that belief is not required for my membership in His family.
