C. F. W. Walther on the Visitation

Each rejoices when another rejoices, and each regards himself as a greater sinner than another. He is therefore honored to receive a visit from even the humblest Christian, for he knows this individual carries within himself the Spirit of the Lord Jesus Christ, just as Mary carried Jesus bodily in her womb. He also knows that, in his fellow Christian, Christ is making a visit. - *God Grant It!* p. 907
