The question asked was, “Can Jesus really live in my heart?” The only place in the Bible where this could be implied is Ephesians 3:17, “so that Christ may dwell in your hearts through faith. Then you, being rooted and grounded in love,” The problem is with the way we understand the words are being used and we miss the context. No, Jesus can’t live in your heart. What Paul is asking in his prayer is for our Creator to strengthen our soul so we are able to establish a greater faith.
