Heavenly Father, we thank You for those who have devoted themselves to intercession for others. We pray that You give them knowledge of Your will and that they will pray accordingly. Give them spiritual wisdom and understanding. Make their prayers fruitful. Strengthen them with all Your glorious power, and give them endurance in their ministry of prayer. Protect them as they take up the weapons of spiritual warfare. May they be filled with joy and thankfulness for answered prayers. Amen.
