I need to break down the word religion into differing ideas:
1 - man made rules which has nothing to do with God or god(s). These are a product of oppression and slavery.
2 - worship of spiritual being(s), which absolutely exist and interact with us in a way that science can not prove it and IMHO never will be able to, but we can perceive if we have faith.
Short answer I don’t know. Here is my take on it:
God has set pattern in His Word and in creation. One such pattern is small things revolving around a central nucleolus, from the atom to the solar system to galaxys, which reflects God and us, He is the center.
Another pattern is the Hebrew day, starting at sundown, is related to creation to present day as presented in scriptures and our personal walk with God:
Beginning:
Hebrew day - twilight fades, still some light, but it grows darker
Creation - Adam and Eve fall away from God and the light of God fades
Us - When God creates us in the places underground and knits us in the womb (Ps. 139:13,15) we feel God’s Love, which fades and it grows dark.
Early
Hebrew Day - Darkness
Creation - Time from the Fall to the flood, this is quite a different world then we know, lifespan is much different, angels much more readily interact with man (in a way perceptible to man). People in spiritual darkness (they don’t know Jesus),
Us - time in womb, quite a different world, we are in spiritual darkness
Deliverance
Hebrew Day - Still darkness
Creation - Flood
Us - Birth
Leading up to Jesus’ birth
Hebrew day - darkness but dawn coming at end
Creation - Time from after flood to the birth of Jesus. People don’t know God directly but go through a prophet or other person. People receive the Law (10 commandments), they try and try and fail and fail to follow them, They get themselves into situations where God gets them out, usually lead by one of His servants, though the people typically grumble. People are still walking in darkness
Us - the time from birth to Jesus being born in out hearts. We go to God through other people (priests), we learn about God’s Law, try to follow them and fail, we cycle through this many times. We get ourselves into situations where God gets us out, usually lead by one of His servants, though the people typically grumble. We still walk in darkness as we still don’t personally know God.
Birth of Jesus, His walk on earth:
Hebrew day: The dawn of light
Creation: Jesus’ birth to ascension, disciples learn about Him, His ways, to trust Him they learn through Jesus Himself. The dawn of the light of the world
Us: Jesus is now available to us, we precieve His person living in His believers. Like the disciples we may not realize that at first, but something about those people attracts you to them. We learn His ways and who He really is. the dawn of light in our life
After ascension:
Hebrew day: walk in the light
Creation: disciples get the Holy Spirit and it is Jesus living in them, they walk in light the rest of their life
Us: we get the Holy Spirit and it is Jesus living in them, we walk in light the rest of our life
To keep that pattern consistent it seemed necessary to reveal things as humanity grows, and the birth of Jesus would have to be somewhere along the way.
Possibly, reading the life of king David we see that he did have the wisdom of angels, and seemed to understand quite a bit about many things that were made much clearer in the NT. The path that Jesus offers is one of grace through faith, that path was always available, it was not just for NT times.
He did reveal things He knew many would not understand, but He is able to overcome this, as He does today, the scriptures are not understandable by men unless revealed by the Holy Spirit.
