Jesus taught in John 4:23-24 that our God is a spirit and desires that we worship Him in spirit and in truth.
Yet the time is coming, and is now here, when true worshipers will worship the Father in spirit and truth. Indeed, the Father is looking for people like that to worship him.
God is spirit, and those who worship him must worship in spirit and truth.”
Look closely at this verse. God is a spirit. And He is looking for people to worship Him in His spiritual realm. To me, this says the spirit realm is truth or reality.
Hebrews 11: 1-3 defines two realities: 1) things that are seen and 2) things that are not seen. The things that are seen represent the physical reality while things that are not seen represent the spiritual reality.
We know that our God exists in this spiritual reality. He created the physical reality or realm, with His spoken word. Things unseen, created the things we see.
Now faith is the assurance that what we hope for will come about and the certainty that what we cannot see exists.
By faith our ancestors won approval.
By faith we understand that time (the age or the world) was created by the word of God, so that what is seen was made from things that are invisible. (NIS. Comment and emphasis mine.)
Look at the same passage in the Amplified version of the Bible:
NOW FAITH is the assurance (the confirmation, the title deed) of the things [we] hope for, being the proof of things [we] do not see and the conviction of their reality [faith perceiving as real fact what is not revealed to the senses].
Heb 11:2 For by [faith–trust and holy fervor born of faith] the men of old had divine testimony borne to them and obtained a good report.
By faith we understand that the worlds [during the successive ages] were framed (fashioned, put in order, and equipped for their intended purpose) by the word of God, so that what we see was not made out of things which are visible.
We, as believers, tend to focus on physical things or the things we can see, when our focus should be placed on the spiritual reality, or things unseen. Our faith (or choosing to walk in faith) is the guarantee that what we hope for, while yet unseen, will manifest into physical reality.
This is why I teach that spiritual health, or a regenerated spirit, must come first. Through faith, our physical and mental health (the things we see) will manifest out of the spiritual realm (the things we don’t see.) In other words, we must connect with God in His spiritual reality first, achieving true spiritual health, then we will receive a blessing in the physical reality.
