The supernatural realm is described as simultaneously being causally connected to the natural world (God can perform miracles in it), and so disconnected from it that it cannot be detected by any means.
This isn’t accurate, God is intimately connected to His creation, He gave authority to mankind to take care of and fellowship with. We rebelled and as a result broke fellowship with God, sin and death was the result. God kept speaking through the Prophets about how He would send His Son. He did come in the flesh. When He rose from the dead and went to Heaven He sent His Spirit to lead and guide us, teach us, enable us to communicate to God the Father through prayer and His Word. He said He was going to return and shared the signs before this would happen. There’s much more but this is all written in the Bible. The naturalistic comments only confirm this scripture to me.
“Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. These things we also speak, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned.”
I Corinthians 2:12-14 NKJV
