There are important personalities in your life that you always bless the day you met them. They might or might not be related to you but they play an important role in your life.
This is a prayer to thank God for such people:
Heavenly Father, thank you for (person’s name). Thank you for creating this person and allowing our paths to cross. I thank you for the series of blessings in their life and for your works which are made evident in their life. I sincerely pray that the world will see the manifestation of your glory which you have created in them. Thank you because you will keep them in perfect peace all the days of their life, Amen.
