This verse is about how Christians should treat each other with humility and respect. It’s part of a bigger section in Paul’s letter to the Ephesians about living a godly life (Ephesians 5:1-20) and leads into advice about relationships like marriage and family (Ephesians 5:22–6:9).   "Submitting yourselves" means choosing to put others first, not because you have to, but because you want to show love and kindness, just like Jesus did (Philippians 2:5-8). The words "one to another" mean everyone in the church should do this for each other, no matter who they are. It’s about working together as equals to build a loving community (Romans 12:10).   The reason for this attitude is "the fear of God," which means respecting and honoring God. It’s not about being scared but about living in a way that pleases Him. When we do this, our actions come from a heart that loves God, not just following rules. This verse teaches that Christians should act with humility and care in all relationships. Instead of trying to be in charge, we should serve others, like Jesus did (Mark 10:42-45). By doing this, we create peace and show the world what God’s love looks like. Ephesians 5:21 calls us to live selflessly, making our churches and homes places of unity and support.
