Quotes from The Philokalia Vol. 1, pg 169

We are not mightier than Samson, wiser than Solomon, more knowledgeable about God than David, and we do not love God better than did Peter, prince of the apostles. So let us not have confidence in ourselves; for he who has confidence in himself will fall headlong.

Let us learn humility from Christ, humiliation from David, and from Peter to shed tears over what has happened; but let us also learn to avoid the despair of Samson, Judas, and that wisest of men, Solomon.

The more the rain falls on the earth, the softer it makes it; similarly, Christ’s holy name gladdens the earth of our heart the more we call upon it.
