Yes the literal temporal, it must be compared to the spiritual unseen, eternal , the unseen understanding to the same kind of understanding. Or faith to faith the gospel . The unseen understanding use literal events .Like the time period of Kings in Israel .
Without parable Christ spoke not.
Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. 1 Corinthians 2:12-13
