(Part 7) Ephesians 3:17 shows that faith is the doorway that allows Christ to dwell, to take up permanent residence, in our hearts. The word katoikeō means “to house permanently,” revealing Christ as the true Landlord of the heart. When He dwells in us, we become rooted and grounded in love, because God is love (1 John 4:8). His indwelling produces a life shaped by His character: self-giving, fearless, and marked by genuine love for others.
