Paul's prayer in Ephesians 3:14-21 reveals God's ultimate plan to unite all things under Christ's authority through the church. As believers, we are not just individuals but part of God's household, serving as His dwelling place and a working model of new creation. Paul prays for spiritual strength in our inner being, that we would be rooted in God's limitless love, and experience His power working through us. When we live as a unified church community, we become a visible sign of God's kingdom that draws others to Christ through our daily lives.
