First of all, I ask Saint Michael and his legion of angels to protect you and keep you safe. I pray that he, through the power of God, opens up windows of time for you to pray and discern in peace and in safety, without distraction.
Lord Jesus, you call only the best to be Your hands and feet in this most special way - the priesthood. If it is Your will for this man to follow you, make Your voice so clear and so strong that it gives him a strength that will last a lifetime.
And a special prayer to your guardian angel to keep watch, keep alert, be mindful to our Lord and to guide you in His path of righteousness, no matter what.
Amen
God Bless you in this period of discernment, and forever.
