Men grow weary of pardoning. They are more severe toward the relapsing sinner, and impose more conditions on him. But the more He pardons, the more merciful does God seem to become. Great sinners who return to Him are His greatest friends. He came for the sick, and for one sinner, He left the angels. Provided there are some humility and confidence in our confession, we are always sure of being welcomed.
--St. Peter Julian Eymard
