Claim. The terminal posture of the filial child is not to receive comfort but to comfort God — to take the cross off the suffering Parent’s back and bear it themselves.
Elaboration. SMM gives the image: “In order to fulfill your duty of filial piety to your Parent who has been toiling strenuously for you, you must first console Him with your tears and then take the cross off His back and go forth, bearing it with dignity. With the heart of proclaiming the fact that the path of the cross God trod for His children has been miserable, you must stand in the position in which you are able to say, ‘Father, please don’t suffer anymore. Father, please don’t worry about me anymore!‘” (CSG 14.7 §2, 31-35, 1970.4.12). The image inverts the usual cross-bearing direction: God has been bearing the cross of fallen humanity, and the filial child’s job is to lift that burden in return. The teaching makes salvation a two-way relationship — God’s children are not just saved but are themselves saviours of God’s anguish.
