Those who persevere…

The joys of this world lead to eternal sorrow; but those who persevere in following the joys that are to be found in the will of the Lord will find themselves led to an enduring, an eternal world.
— Ambrosiaster (Fourth Century)

No matter what obstacles..

Let us stir up our hearts, rekindle our faith, and long eagerly for what heaven has in store for us. To love thus is to be already on our way. No matter what obstacles we encounter, we must not allow them to turn us aside from the joy of that heavenly feast. Anyone who is determined to reach his destination, is not deterred by the roughness of the road that leads to it.
–Saint Gregory the Great (c. 540-604)
