24. Supported by this faith, even he who is weak shall prevail, and his soul will be holy, and the prophetic or apostolic mountains shall _drop down new wine_ for him, and _the hills shall flow with milk_, like that hill which gave milk to the Corinthians to drink, and water shall flow for him from their vessels, and from their well-heads. _From his belly shall flow living water_, that spiritual water which the Holy Spirit supplies to His faithful; may He vouchsafe to water thy soul also, that in thee may be _a fountain springing up into life eternal_. Farewell: love me as a son, for I love you as a father. LETTER XXX. A.D. 389. S. AMBROSE here continues the subject of the last Letter, dwelling especially on the duty of rising above the level of earthly things, and bringing together various passages of the Old Testament which he interprets spiritually as setting forth this Lesson. The true follower of Christ will build Him a Temple in his heart, which his Lord will fill with the adornment of spiritual graces. AMBROSE TO IRENÆUS, GREETING. Sidenote: Hag. i. 4. Sidenote: Ib. 2. Sidenote: Ecclus. xxiii. 18. 1. AFTER I had finished my last letter and directed it to be conveyed to you, the words which the Lord spake by the prophet Haggai came into my mind, _Is it time for you, O ye, to dwell in your cieled houses?_ What is the meaning of this but that we ought to dwell on high, not in low and subterranean abodes? For they who dwell beneath the earth, cannot build the temple of God, but say, _The time is not come, the time that the Lord’s house should be built_, because it is the mark of sensual persons to seek underground dwellings, courting the cool of summer, being enervated by indulgence and requiring shady retreats to enable them to bear the heat, or because the slothful live at ease beneath the earth, or lastly because dark and shady places suit them best, concealing, (as they believe,) their crimes. _I am compassed about with darkness, the walls cover me, what need I to fear?_ But in vain do they hope for this, when God beholds the hidden depths of the abyss, and discovers all things before they take place.
