This divine order, established since creation, ensures that lower beings are upheld, nourished, and guided through intermediaries to the higher realms.
As Blessed Augustine notes, the angelic presence indeed fights alongside those who revere God, as reflected in Hebrews 1:14, which declares that angels are “ministering spirits sent forth to minister for those who shall be heirs of salvation.” This belief is echoed in the prayers of the faithful who cherish piety and the fear of the Lord. For instance, blessed Jacob, when blessing Joseph's children, invoked, “The angel who delivers me from all evils, that he may bless these children” (Genesis 48:16). Similarly, when Abraham commissioned his servant to find a bride for Isaac, he expressed confidence in God’s assurance: “The Lord God will send His angel before thee, and thou shalt find a wife for my son Isaac” (Genesis 24:7). To further illustrate this principle, one can recall how angels protected Jacob from Esau (Genesis 32:1) and how the angel of death struck down 180,000 foes besieging Jerusalem during King Hezekiah’s reign.
From the moment of baptism, believers are assigned a Guardian Angel. St. Basil the Great assures us that this angel remains with the faithful unless they drive him away through sinful actions. Just as bees are repelled by smoke and doves by foul odors, the Guardian Angel departs when beset by numerous sinful deeds. Yet, when a soul is adorned with acts worthy of divine protection and contemplates truth, God's grace activates angelic guardianship, promising comprehensive protection. An angel is said to possess the strength of an entire army, serving as an impenetrable defense, much like city walls that repel an enemy's assault. Thus, “A thousand shall fall at thy side and ten thousand at thy right hand; but it shall not come near thee: for He shall give His angels charge over thee” (Psalm 91:7, 11).
In light of the protective vigilance of God's angels, it is both reasonable and essential for us to seek their intercession through prayer. They surround us and heed our petitions much like devout individuals living among us who we ask to intercede on our behalf. As they are spiritual beings, they perceive our souls and the inclinations of our hearts, responding accordingly. When negative thoughts arise, the Angel of God assists in resisting such thoughts, without infringing upon our free will. The angel remains steadfast, guarding against malign influences as long as the soul is not inclined toward the harmful thought. However, should the soul entertain such thoughts, the angel withdraws, allowing unclean spirits to exert their influence, urging the soul to fulfill its dark inclinations.
