There are many things the Lord does through the ministry of angels. The following are a few out of the many—
Angels guide in difficulty, as seen in Eleazer's mission. "He shall send His angel before thee" (Gen 24:7, 40).
Angels deliver from evil, as Jacob testifies. "The Angel which redeemed me from all evil" (Gen 48:16).
Angels commission in work, as is evidenced in Gideon. "There came an angel of the Lord" (Jdg 6:11, 22).
Angels encourage in despondency, as we gather from Elijah when under the juniper tree. "As he lay and slept under a juniper tree, behold then an angel touched him, and said unto him, Arise and eat" (1Ki 19:5, 7).
Angels shield from harm by their presence, as David assures us. "The angel of the Lord encampeth round about them that fear Him, and delivereth them" (Psa 34:7).
Angels defeat our adversaries, as we have illustrated in Hezekiah's deliverance from Sennacherib. "Then the angel of the Lord went forth and smote in the camp of the Assyrians," &c. (Isa 37:36).
Angels preserve in the midst of danger, as we have demonstrated in the cases of the three Hebrew young men and Daniel. "Who hath sent His angel and delivered His servants" (Dan 3:28; Dan 6:22).
