Lord told us to pray…

The Lord told us to pray in secret – that means in your heart – and he instructed us to “shut the door.” What is this door he says we must shut, if not the mouth? For we are the temple in which Christ dwells, for as the Apostle said: “You are the temple of the Lord.” And the Lord enters into your inner self into this house, to cleanse it from everything that is unclean, but only while the door — that is, your mouth – is closed shut.
–Saint Aphrahat the Persian 270-345)
