In Matthew 6:33, the lesson is about putting God first in our lives. It teaches that if we seek God and His ways, He will take care of our needs.
For a morning devotion prayer based on Matthew 6:33, you could say:
"Dear God, help us to seek You first today and in everything we do. Guide our thoughts and actions so that we align with Your will. We trust that You will provide for our needs. Amen."
