One-line prayers

I was inspired by a video (below) to share these simple one-line prayers that are easy to say when you need them. These are simple prayers that you can repeat over and over to great effect in your life. If you can't remember any other prayers, keep these in mind.

Note:  "To pray" means "to ask". (It is NOT worship.) You are asking, making a request. Requesting the Lord's mercy or the intercession of His Blessed Mother is very powerful in our lives.

Most precious blood:
Most precious blood of Jesus Christ, save us and the whole world.

Jesus prayer:
Lord Jesus Christ, son of God, have mercy on me, a sinner.

Surrender prayer:
Jesus, I surrender myself to thee, take care of everything.

Miraculous Medal:

O Mary, conceived without sin, pray for us who have recourse to thee.
