Non-physical world? ... First God created the dimensions, then He used light to get physical things going. Anything in God’s universe will have a where/when realm, whether we can now sense it or not. You might be better off stating non-visual, as in non-visual with our present physical configuration. But Jesus has told us that He is preparing a place for us and He shall come again to take us ‘there’, to that where/when. We have hints of that possibility with the fifth chapter in Daniel, the Old Testament/Tanakh. Whomever wrote on Belshazzar’s wall at palace party central was in a where/when and reached into Belshazzar’s where/when. Angels exist in some sort of where/when.
Certainly I think so, dear brother in Christ!
They are not as spatio/temporally remote from us as we may think....
JMHO. FWIW.
