Selected quotes from St. Simeon the New Theologian:

"Faith is (readiness) to die for Christ's sake, for His commandments, in the conviction that such death brings life."

"Faith in Christ is... a good and patient disposition of the soul in enduring all temptations, whether griefs, sorrows or unpleasant happenings, until God's favour looks down upon us; thus we would imitate David who says: 'I waited patiently for the Lord; and He inclined to me and heard my cry' (Ps. 40:1)."

"...nothing pleases God more than when we hasten to obey His will."
