"For this reason we also, since the day we heard it, do no cease to pray for you, and to ask that you may be filled with the knowledge of His will in all wisdom and spiritual understanding; that you may walk worthy of the Lord, fully pleasing Him, being fruitful in every good work and increasing in the knowledge of God."
Colossians 1:9-11
Praying with purpose is powerful. Asking for Godly behavior and character in people is the sweetest gift you could give them.
Praying with purpose is persistent. If you are going to pray, EXPECT God to move.
