There’s some crazy stuff in the Bible. Especially this business about slaves, masters, and submissive wives. We could certainly spend time discussing the nitty-gritty of these things; they’re valid and important discussions. But if we look at the crazy verses from a crazy perspective, we get… crazy.
The book of Colossians is one letter. Long after the letter was written chapters and verses were inserted as an organizational tool for the reader. They are there to make it easy for us to reference specific points, NOT take each verse outside the context of the other. This is why good Biblical interpretation will interpret scripture in light of scripture.
At the very beginning of the letter, Paul explains the gospel as the starting point that he is going to explain everything else from. Therefore, the gospel is what we should approach all things with. He says that everything was made 1) by Him, 2) through Him, 3) is for Him, and, here’s the best news: 4) He reconciles ALL things to Himself, thus making us free (which he talks about in chapter 2).
In chapter 3, Paul gives all sorts of situations and roles we may find ourselves in - marriage, occupational, within a family. Here’s how we should approach them:
“…Clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive whatever grievances you may have against one another. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity. Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. Let the word of Christ dwell in you richly as you teach and admonish one another with all wisdom, and as you sing psalms, hymns and spiritual songs with gratitude in your hearts to God. And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.” - Paul
Why? Because we are God’s chosen ones. Holy. Beloved. Free.
