Lord have this person get more into reading your holy word to learn wisdom and gain strength to keep all thoughts of jealousy away from them. May they concentrate more on you than in what's going on in other people's life so they won't have any room for envy or jealousy in their own life. May they allow you to guide their steps from now on for if you are really in their heart there shouldn't be any jealousy but love for others. I pray in your most holy name Jesus of Nazareth, amen.
