Psalm 9:11 “Sing praises to the Lord, who dwells in Zion! Declare His deeds among the people”
Contemplation by Saint John Chrysostom:
He wants them [the Faithful] to be heralds of God’s favours, and never conceal his favours. He always looks for this, for the sake of both the speakers and of the listeners; it is of benefit to latter and former, after all, provided they give heed.
