Otherwise, what does God say righteous legitimacy is in relationships? Well for starters, I want to look at the relationships within the Bible. Let's consider Abraham and Lot, the little nephew of Abraham. Lot was a pretty dastardly character, not only was he lazy, but he had some serious issues regarding territorialness, and comfort. His relationship with his uncle was one I might consider to be a codependent/enabler type of relationship certainly because of the fact that Abraham never truly challenged him to live above the standard by which he was living. And yet the relationship stuck, and when Lot was needing help and Abraham was involved he was sovereignly saved by the Lord where he easily could've been turned to salt like his wife.
But we must consider the fact that because he knew Abraham, and Abraham knew him, he was saved. In God's eyes I can't help but feel that he considered the relationship legitimate because of Abrahams love for his little cousin.
How about the relationship between Jesus and Judas? Jesus himself was so good at processing his emotions that even though he KNEW Judas was going to betray him he still wanted to have him around. What legitimized that relationship? Well I might point to the exact thing that I said just before, Jesus liked and desired to spend time with Judas. Even in the midst of his very toxic heart, Jesus enjoyed his company. Judas didn't know it or receive it, but had he known I'm sure the world would be much different, and the story we know very changed.
There's plenty of examples to look at as far as relationships, Moses and Aaron, Moses and Joshua, David and Nathaniel, Jeremiah and Baruch. As this thought develops I might like to deep dive into each of these individually. Otherwise, here is where we're at for now.
