Father Girardey gives several reasons why we ought to pray. The first is because we are children of God.
He writes: “We are made for heavenly bliss, and nevertheless, of ourselves we can do nothing to gain it, to merit it, to attain the place destined for us in Heaven, for our divine Saviour expressly declares: ‘Without Me you can do nothing’ (John 15:5). . . . If God Himself assists us with His all-powerful grace, we can assuredly gain, deserve and reach ‘our place in Heaven’ and forever enjoy its ineffable bliss, according to the express saying of St. Paul: ‘I can do all things in Him who giveth me strength’ (Phil 4:13). And here we should from our inmost heart thank the boundless mercy, goodness and love of our Father in heaven, who will most willingly help us, if we but pray to Him and invoke His help in our wants, in all that conduces to our gaining possession of ‘our place in Heaven.’ . . . God’s necessary help will be given us and will enable us to perform all that is necessary for our salvation.”
“Our dependence on God is so entire and complete, that, without His constantly preserving hand, we could not exist even for a moment, but should of ourselves at once relapse into nothingness. . . . As our Father, He deserves all our respect, honor, obedience, confidence and love.”
“The humble and faithful servant of God is the noble and glorious conqueror and master of himself; he rules over his passions, over mere human views and human respect, over the world and its allurements and vanities; he is, therefore, free and independent of all that is below him, and enjoys the true liberty of the children of God, which consists in being wholly subject to the authority of God, from whom alone all genuine power and authority on earth are derived, as St. Paul teaches: ‘There is no power but from God’ (Rom 13:1). To own our total dependence on God and His absolute authority over us, and to declare this to Him is prayer.”
