Of us God demands purity of heart, that purity which is the life of the soul. He wants besides, since we possess no virtues worthy of Him, a deep respect and true humility. Let us say to Him: " Lord I am not worthy to receive Thee. Depart from me, for I am a miserable sinner!" This conviction makes up for our shortcomings. Our Lord is content with it and, when he comes to us, He will give us all that we lack. Let us simply be faithful, humble, and confident. He will do the rest.
St. Peter Eymard
