At the beginning of our religion class, we say the Prayer of St. Ignatius of Loyola. St. Ignatius asks the Lord for nothing but His love and compassion. We ask God to take all of what we have because God is all we need. He gives love, understanding, and guidance.
God gives these things and we offer them back as an offering. God alone and His presence is all we need.
And had Caesar learned that his soldier submitted himself to someone's "word," that Centurion's head would roll in no time! At that time, only Caesar could "say the word" and everything moved. See?
It was humility. How many of us have such kind of humility these days?
Think about it, if that Centurion had that amount of love for his servant, how much more love do you think he had for his own family?
Think about it. May we all have twice the faith, love and humility of that Centurion.
