Brethren in Christ, I find among many brethren one of the most difficult things written in God's Word they seem to lack instruction on is how God's Word, and all languages for that matter, use symbols, metaphors, allegory, idioms, expressions, parable, etc., to give a deeper understanding of a literal thing or literal event.
Instead, what I see with Bible interpretation by some, is they create yet another metaphor from a symbol or allegory, when the metaphor was designed to make the subject easier to understand.
Here's an example, and it is a hard one for many to understand, yet it was Lord Jesus' explanation:
In Matthew 13, Jesus gave His parable of the tares of the field to the multitudes. Then later, when He and His disciples went into the house in private, they asked Him to 'explain' the parable to them. Jesus then gave the explanation, not another parable, but an explanation...
In His explanation, Jesus said the good seed represented the children of the kingdom, and they were sown by the Son of Man.
But He said the tares were the children of the wicked one, and the enemy that sowed them was the devil.
That's kind of difficult to believe, isn't it, that Jesus and the devil sowed children for this present world? Is that just another metaphor? It's actually a spiritual metaphor, pointing to a literal event that happened. Do you recall in Ephesians by Apostle Paul that Christ's chosen elect were chosen before the foundation of this world? That's what Jesus' idea of sowing children is about, the predestination of His elect vs. the predestination of the devil's elect, before the foundation of this world. Genesis 3:15 even hinted at it early in God's Word with the concept of the devil's seed vs. the Seed of the Woman (symbolic for Christ's family lineage).
Likewise with Lord Jesus' parable that you don't put new wine in old bottles lest the bottles break, but put new wine in new bottles so both are preserved. In reality, Jesus was pointing to wine skins, which is what they used at the time. And He was using the idea of wine and the wine skins as symbols; wine for His Truth and wine skins for those hearing His Word.
The idea of new wine is about freshly made fermenting wine. While it is fermenting it must have room to expand and contract. If you put it in an old dried out wine skin, the skin will burst, because the dried out skin cannot expand to keep it. Likewise, if one tries to teach the New Wine of God's Word, meaning full strength, folks who are set in their ways with heeding men's traditions will be like the dried up wine skins. Their understanding just cannot handle it. By this Lord Jesus was suggesting to find new wine skins, i.e., people that had not been subjected for years to the traditions of men, and they would receive Him and His Truth full strength.
Therefore, metaphors, allegory, analogy, parable, etc., in God's Word is not to make understanding more difficult, but to make understanding His Word easier to understand. Remember the old saying, "A picture is worth a thousand words." That is what symbols and metaphors do.
