O just and glorious St. Joseph, I incessantly entrust to you the salvation of the soul of < person's name here >, redeemed at the cost of the precious Blood of Jesus.
You, great saint that you are, know how unhappy are those who, having banished the Divine Savior from their heart, are in danger of losing Him for all eternity.
Therefore, do not allow this soul who is so dear to me to be separated very long from Jesus.
Make him/her recognize the dangers that threaten him/her.
Speak firmly to his/her heart. Lead back this prodigal son to the embrace of the best of parents and do not leave him/her until You have opened the gated of heaven, where he/she will bless You eternally for the joy that You have given him/her.
