"God allows us to give rise to the practice of two beautiful virtues: perseverance, which leads us to attain the goal, and constancy, which helps us to overcome difficulties." St. Vincent de Paul

There are human virtues and there are spiritual virtues. The former are part of our natural, human state. The latter are gifts from God to go beyond what our human ability alone can achieve. Sometimes the task before us seem impossible to reach. Praying for the grace of perseverance enables us to have a spiritual boost of energy to push forward. The grace of constancy or steadfastness enables us to keep our eyes on the Lord, rather than on the struggle. God' help is always available to us. All we have to do is believe and ask for it, relying on him in all things.
