St. Bernard

Calling the saints to mind inspires, or rather arouses in us, above all else, a longing to enjoy their company, so desirable in itself. We long to share in the citizenship of heaven, to dwell with the spirits of the blessed, to join the assembly of patriarchs, the ranks of the prophets, the council of apostles, the great host of martyrs, the noble company of confessors and the choir of virgins. In short, we long to be united in happiness with all the saints.

St. Faustina

O my Jesus, I have only one task to carry out in my lifetime, in death, and throughout eternity, and that is to adore Your incomprehensible mercy. No mind, either of angel or of man, will ever fathom the mysteries of Your mercy, O God. The angels are lost in amazement before the mystery of divine mercy, but cannot comprehend it. Everything that has come from the Creator's hand is contained in this inconceivable mystery; that is to say, in the very depths of His tender mercy. When I meditate on this, my spirit swoons, and my heart dissolves with joy. O Jesus, it is through Your most compassionate Heart, as through a crystal, that the rays of divine mercy have come to us.

Jesus

For everyone who exalts himself will be humbled,
but the one who humbles himself will be exalted.

St. Cyril of Alexandria

It was not otherwise possible for man, being of a nature which perishes, to escape death, unless he recovered that ancient grace, and partook once more of God who holds all things together in being and preserves them in life through the Son in the Spirit. Therefore His only-begotten Word has become a partaker of flesh and blood (Heb. 2:14), that is, He has become man, though being Life by nature, and begotten of the Life that is by nature, that is, of God the Father, so that, having united Himself with the flesh which perishes according to the law of its own nature...He might restore it to His own life and render it through Himself a partaker of God the Father....And He wears our nature, refashioning it to His own life. And He Himself is also in us, for we have all become partakers of Him, and have Him in ourselves through the Spirit. For this reason we have become "partakers of the divine nature" (2 Pet. 1:4), and are reckoned as sons, and so too have in ourselves the Father Himself through the Son.

St. Therese of Lisieux

Joy isn't found in the material objects surrounding us, but in the inner recesses of the soul. One can possess joy in a prison cell as well as in a palace.

A Prayer from the Divine Office

God our Father,
You conquer the darkness of ignorance
by the light of Your Word.
Strengthen within our hearts
the faith You have given us;
let not temptation ever quench the fire
that Your love has kindled within us.
We ask this through our Lord Jesus Christ, Your Son,
Who lives and reigns with You and the Holy Spirit,
one God, for ever and ever.
Amen.

St. Francis de Sales

Perfection of life is the perfection of love. For love is the life of the soul.
