Why doesn't the Bible just say so?
This is a recurring issue with the Bible,
I’ve made the same observation. Well thought!
For example in John 1:1: “The Word was God.” And other scriptures too, some are symbolic, Jesus coming in the clouds of heaven—which is also an allusion to the prophecy of the Messiah in Daniel which JW interpret that the return of Christ is invisible. But the Bible is left to interpretation. That’s the way the entire Bible is written-in poetic language, (even historical accounts have in addition poetic meaning for example Haagar and Sarah) except where it does define and explain meanings such as when Jesus explains who is the prophetic Elijah or clarifying the meaning of the “disgusting thing causing desolation” are the Roman Armies and then it has an additional interpretation applying to the attacker of false religion in our time.
You have to figure everything out like trying to solve a picture puzzle and crossword puzzle at the same time. And you run into major problems like with the meaning of generation which the Bible defines is 80 years the average age of a person —and then this fails when applying to Jesus’s prophecy —which leads you to doubt your other parts of the puzzle you’ve solved as certainly true. Even what happens at death and who goes to heaven are conclusions. It all makes logical sense though—JW interpretation of the Bible—to the point of being mentally and emotionally convinced to the point of dying for your beliefs such as blood and political neutrality.
