Lord give this person the assurance they need to know who they are in you. To make you the rock of their life, so
no matter what this other person or anyone else says to them, it won't bother this child of yours. For they know they are a new creation in you and your child. Have this bully person come to repentance and make you Lord and Savior of their life too. Have your perfect will be done in this situation and this person's life. I pray in the mighty name of Jesus Christ Amen.
