Perfection consists in one thing alone, which is, doing the will of God. For, according to our Lord’s words, it suffices for perfection to deny self, to take up the cross and to follow Him. Now, who denies himself and takes up his cross and follows Christ better than he who seeks not to do his own will, but always that of God? Behold, now, how little is needed to become a Saint! Nothing more than to acquire the habit of willing, on every occasion, what God wills. -St. Vincent de Paul
More than in anything else the Saint just quoted showed the purity and solidity of his virtue, in always aiming to follow and obey the will of God. This was the great principle on which all his resolutions were founded, and by which he faithfully and firmly carried them into practice, trampling under foot his own interest, and preferring the Divine will and the glory and service of God to anything else, without exception.
As his profound humility made him believe himself incapable of great things, he thought only of fulfilling faithfully towards God the obligations of a true and perfect Christian.
The Lord said of David, that he was a man after His own heart; and the foundation for such high praise is given in these words, “for in all things he will do My will.”
