How do I make this prayer more effective?

Prayer is most effective when done with a sincere heart and consistency. Establish a quiet time, focus on God's presence, and speak honestly. Combining the "St. Alphonsus De Liguori's Short Act of Perfect Love" with fasting or reading Scripture can also deepen your spiritual experience.

Can I pray this prayer for someone else?

Absolutely. Intercessory prayer (praying for others) is a powerful act of love. Simply mention the person's name and intention as you pray, asking God to pour His grace upon them.
