Certainly amongst all devotions, after that of receiving the sacraments, that of adoring Jesus in the Blessed Sacrament holds first place, is most pleasing to God, and most useful to ourselves. Do not then, O devout soul, refuse to begin this devotion; and forsaking the conversation of men, dwell each day, from this time forward, for at least half or quarter of an hour, in some church, in the presence of Jesus Christ under the sacramental species. Taste and see how sweet is the Lord.
Alphonsus LiguoriJesus is the mediator of justice; Mary obtains for us grace; for, as St. Bernard, St. Bonaventure, St. Bernardine of Siena, St. Germanus, St. Antoninus, and others say, it is the will of God to dispense through the hands of Mary whatever graces he is pleased to bestow upon us. With God, the prayers of the saints are the prayers of His friends, but the prayers of Mary are the prayers of His mother.
Alphonsus LiguoriWithout prayer it is impossible to resist temptations and to keep the commandments.
Alphonsus LiguoriWhoever prays is certainly saved. He who does not is certainly damned. All the blessed have been saved by prayer. All the damned have been lost through not praying. If they had prayed they would not have been lost. And this is, and will be their greatest torment in hell: to think how easily they might have been saved, just by asking God for His grace, but that now it is too late - their time of prayer is gone.
