To try and find meaning in the Bible I suggest, is entirely the wrong approach. “Why was it written down?” is the question to ask.
The text attributed to Paul refers to the deep things of God, what was it?
Answer: Early Christianity was a superstition in a very long tradition of mystery cults. The outline myth being that the saviour (a demi-human Sun God) died and was sacrificed at Easter on behalf of humanity and went his way to his Sun-God father and they both shone radiantly and triumphantly their heavenly realm having conquered the darkness of winter...as the sun conspicuously does after the spring equinox.
All the ancient god-man mystery cults followed this myth. To become a communicant in the cult would originally have required you to go through an initiation process into the “sacred secrets”, to learn the “deep things of God.” It was usually performed in a long and complex ritual which involved passing through unlit subterranean chambers, stair wells and trap doors. The idea was to create intense fear in the novice and dependency on the spiritual leader. Over time and after enough rituals you too might make the grade of high priest. Incidentally in the Dionysian christ-cult one of the names the initiate took on was "Iasus". There were various levels of initiation, as retained (or imitated) in Free Masonry today, there were also levels of heaven to which the Bible writer Paul referred in his brand of mystery cult. (Funny how nobody picks up on this undiluted paganism?)
So the deep things of God were a reference to the exclusive things which only the cult hierarchy were privy to. It was for for the initiated only...(like those who believe in the sacred but unbiblical Watchtower mystery of 1919!)
Then why was it written down? To bamboozle the ignorant and poor so they reverence the “holy” mysteries and thereby become slaves under the control of the religious hierarchy.
Punky does this help at all?
