We are a people with hearts of stone, hearts as hard as a street pavement; the life of Christ leaves not a trace on them. Therefore, if we wish to be saved, our hearts must be tender, sensitive, enlivened; our hearts must be contrived, ploughed like soil, dug up, watered, tended, cultivated, until they become like a garden, a garden of Eden, worthy of the approval of our God, gardens in which the Lord God will be able to walk, in which He will be able to dwell; gardens filled not with wild bushes and thorns, but with fragrant and useful saplings of heavenly trees and flowers. Deserts and barren wastelands must be irrigated by streams of living water.
