Parallelism, it seems this is a concept all people who study the Bible aren't familiar with. This just means two things are similar but not exactly the same. For example two cars might parallel parked. In the same direction on the same street, but they aren't the same car, perhaps not even the same make of car. Two lines on a page can be parallel to each other, go the same direction, perhaps be the same length or color, but obviously they can't occupy the same space on the page. Some churches teach this, some churches say it is blasphemy. Perhaps the most common example of this is the book of Ruth. To some, it's just a random story of a widow who married a relative. Now why would this story be in the Bible? Well for one thing it's part of David and Jesus' lineage, so that might be part of it. Ruth was Jesus' great, great... (add a few more greats here) grandmother. We also know that Ruth was a Gentile (Moabite) who believed in God, so maybe that is another purpose for the story, to show some Gentiles believed in God. Also this means that Jesus was part Gentile way back in his earthly ancestry. But perhaps this story is a lot more than that, some believe it is a story about a "kinsman-redeemer". They believe Boaz to be a type of Christ. In that he was a blood relative of Ruth. Rom 1:3; Heb 2:14 He paid the price for a forfeited inheritance. 1 Pet 1:18-19 He was willing to redeem her. Heb 10:7 This is an example God caring for his people. Ruth 2:12 Perhaps this story reveals part of the very nature of God and his love for us. Another example of this is the book of Hosea. Perhaps it's just a book about a Prophet with an unfaithful wife during a time when Israel was repeatedly unfaithful to God. ..or, perhaps it's a story about God's faithfulness to Israel even when Israel was unfaithful to him. Again, revealing part of the very nature of who God is. There are at least a dozen or so other examples in the Bible, Another common one is Ezekiel 28, some believe this to be a story only about the King of Tyre. Others believe him to be a type of Satan, A description of this person is likened to a description of Satan himself. Some say these things "are the mysteries of the kingdom of Heaven" (Matt 13:11; Luke 8:10; 1 Cor 4:1 ) that only only be known if the Holy Spirit reveals them to you. Others say it's adding meaning to the Bible that isn't really there. All I can say is, pray about it and see what God reveals to you.
