What does Ephesians 3:17 mean?

Paul famously speaks eloquently of faith, hope, and love at the conclusion of 1 Corinthians 13. Here, he mentions two of these attributes. First, his desire in this passage is for growth in faith, rather than knowledge, though both are important. Ephesians 2:22 also used the idea of a "dwelling place for God by the Spirit." Paul similarly taught the Colossians, "Let the word of Christ dwell in you richly" (Colossians 3:16).

Second, Paul prays his readers will be secure in their reliance on love. The imagery is that of a tree held strongly by deep roots (Matthew 13:6, 21; 15:13; Mark 4:17). Love, especially shown between fellow Christians, is meant to be the hallmark of our faith (John 13:34–35). Love is likewise meant to keep the Christian grounded, staying in place with Christ and growing us to maturity. Colossians 2:7 speaks similarly of being "rooted and built up in him and established in the faith."
