To serve God you…

If you want to serve God, prepare your heart not for food, not for drink, not for rest, not for ease, but for suffering, so that you may endure all temptations, trouble and sorrow. Prepare for severities, fasts, spiritual struggles and many afflictions, for “by many afflictions is it appointed to us to enter the Kingdom of Heaven” (Acts 14,22); “The Heavenly Kingdom is taken by force, and the who use force seize it“. (Matt 11:12)
— Saint Sergius of Radonezh (1314-1392)

 

The stronger our faith…

So the stronger and the more vehement our faith in God is, and the more reverently and persistently it is offered up to God, the more surely, the more abundantly and the quicker what we hoped for will be accomplished and obtained.
— Saint Albert the Great (c. 1206-1280)

Why do you delay…

Why do you delay, why are you afraid? Believe, give praise, and receive. Let humility be bold, let modesty be confident… See, the desired of all nations is at your door, knocking to enter. If he should pass by because of your delay, in sorrow you would begin to seek him afresh, the One whom your soul loves. Arise, hasten, open. Arise in faith, hasten in devotion, open in praise and thanksgiving.
–Saint Bernard of Clairvaux (1090-1153)
