'Existence' in the Bible

For it was fitting for God [that is, an act worthy of His divine nature] that He, for whose sake are all things, and through whom are all things, in bringing many sons to glory, should make the author and founder of their salvation perfect through suffering [bringing to maturity the human experience necessary for Him to be perfectly equipped for His office as High Priest].

They serve as a pattern and foreshadowing of [what has its true existence and reality in] the heavenly things (sanctuary). For when Moses was about to erect the tabernacle, he was warned by God, saying, “See that you make it all [exactly] according to the pattern which was shown to you on the mountain.”
