The Lord has told different saints what He will do in return for souls who honour His Face. With St. Gertrude  He said; “They shall receive in themselves, by impression of My humanity, a bright irradiation of My divinity, and shall be so illuminated by in their inmost souls that, by their likeness to My face, they shall shine in eternal life with a brightness surpassing that of many others.”

With St. Mechtilde He said;”Those who embrace this work of reparation with true piety  will not be lost, for I Myself will defend them before My Father and I will give them the Kingdom of Heaven. I will grant them the grace of final perseverance.

With Sr. Mary of St. Peter He said; He would imprint His divine likeness upon the souls of those who honour the features of His face. And also He said “you will obtain the conversions of many sinners. Nothing that you ask in virtue of the Holy Face  will be refused you. Oh, if you only knew how pleasing Is the sight of My Face to My Father.  (I just want to add I have seen a vision of how pleasing it is for Our Heavenly Father, when we also offer up Jesus’s Heart. He is so pleased He doesn’t even look at the prayer that you want answered. Our Father just automatically accepts it.)

Jesus also said to Sr. Mary of St. Peter. “In proportion to the care you take in making reparation to My face, disfigured by blasphemies. I will take care of yours, disfigured by sin. I will imprint My image on it and render it as beautiful as when it was washed in the waters of Baptism.”

There are many other promises, but I thought these were all we need, so as to get the idea how pleasing to Our Lord when we appreciate Him, the kind of rewards He hands out to everybody.  You can always pray and worship Him with your own words and I think they are the most powerful of all, because it comes from your heart, therefore it is not just a habit you got into.  Below is a prayer in honour of Jesus Face, if you choose to say it.

Eternal Father, turn away Your angry face from all guilty people whose faces have become unsightly  in Your eyes. Look instead upon the face of Your Beloved Son, for this is the Face of Him in whom You are well pleased. We now offer You this holy Face, covered with shame and disfigured by bloody bruises, in reparation for the crimes of our age, in order to appease Your anger, justly provoked against us. Because Your divine Son our Redeemer, has taken upon His head all the sins of His people that they might be spared, we now beg of You, Eternal Father, to grant us mercy. Amen

I got all this from a book I have just bought called Prayers and heavenly promises.
