Pope Francis uses a very familiar New Testament image:
136. True enough, we need to open the door of our hearts to Jesus, who stands and knocks (cf. Revelation 3:20).
Standing the image on its head, as the pope often does:
Sometimes I wonder, though, if perhaps Jesus is already inside us and knocking on the door for us to let him escape from our stale self-centeredness. In the Gospel, we see how Jesus “went through the cities and villages, preaching and bringing the good news of the kingdom of God” (Luke 8:1).
Again, a most important aspect of the Gospel: getting beyond narcissism and engaging others through a genuine encounter.
After the resurrection, when the disciples went forth in all directions, the Lord accompanied them (cf. Mark 16:20). This is what happens as the result of true encounter.
