A guardian angel is appointed to every follower of Christ. These heavenly watchers shield the righteous from the power of the wicked one. This Satan himself recognized when he said: “Doth Job fear God for nought? Hast not Thou made an hedge about him, and about his house, and about all that he hath on every side?” Job 1:9, 10. The agency by which God protects His people is presented in the words of the psalmist: “The angel of the Lord encampeth round about them that fear Him, and delivereth them.” Psalm 34:7. Said the Saviour, speaking of those that believe in Him: “Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of My Father.” Matthew 18:10. The angels appointed to minister to the children of God have at all times access to His presence.
Thus God’s people, exposed to the deceptive power and unsleeping malice of the prince of darkness, and in conflict with all the forces of evil, are assured of the unceasing guardianship of heavenly angels. Nor is such assurance given without need. If God has granted to His children promise of grace and protection, it is because there are mighty agencies of evil to be met—agencies numerous, determined, and untiring, of whose malignity and power none can safely be ignorant or unheeding.
