To be like children in his kingdom.

There is no choice but to continue on the path day by day and hold God's hand. Your journey is one of a child's heart, not childish – childhood never leads to anything good – but the heart of childhood rediscovered in surrender to God and in various trials, whatever they may be, in the tests that He prepares for each of us, so that we can "be like children in His kingdom," so that "His kingdom may come" as He wishes.

(Cardinal Charles Journet /1891–1975/, correspondence)
