The Apostle now points out to us the hidden man of the heart (I Peter 3:4) as the object of our most painstaking concern and care. We are to adorn ourselves through the formation of this man within ourselves. What is the meaning of the hidden man of the heart? It is that man which forms in the heart when only good dispositions and feelings come to dwell therein. Examine these dispositions and feelings, and you will see the face of the man hidden in the heart. Here are these dispositions: His Divine power hath given unto us all things that pertain unto life and godliness (II Peter 1:3), and on your part, giving all diligence, writes St. Peter, add to your faith virtue; and to virtue knowledge; and to knowledge temperance; and to temperance patience; and to patience godliness; and to godliness brotherly kindness; and to brotherly kindness love (II Peter 1:5-7). In a similar fashion St. Paul lists the inner good dispositions of the Christian heart: The fruit of the Spirit is love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, temperance (Gal. 5:22-23). Also: Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, and above all these things put on love, which is the bond of perfectness. And let the peace of God rule in your hearts (Col. 3:12-15). Bring together all of these good things into one spiritual body with its various members, and you will see the divinely beautiful Face of the hidden man of the heart. You must fervently establish the same in your own heart.

Great and Holy Wednesday — Prophet Jeremiah
Celebrating the memory of Your Prophet Jeremiah, O Lord, for his sake, we entreat You to save our souls.
Kontakion, Tone 4
Cleansing your radiant heart through the Spirit, O great Prophet and Martyr, glorious Jeremiah, You received from on high the gift of prophecy. You cried out with a great voice to the nations: This is our God, and there is none other beside Him who became incarnate and appeared on earth.
