Joshua 5:13 When Joshua was by Jericho, he lifted up his eyes and looked, and behold, a man was standing before him with his drawn sword in his hand. And Joshua went to him and said to him, “Are you for us, or for our adversaries?” And he said, “No; but I am the commander of the army of the Lord. Now I have come.” And Joshua fell on his face to the earth and worshiped and said to him, “What does my lord say to his servant?” And the commander of the Lord’s army said to Joshua, “Take off your sandals from your feet, for the place where you are standing is holy.” And Joshua did so.
Exodus 23:20-22 “Behold, I send an angel before you to guard you on the way and to bring you to the place that I have prepared. Pay careful attention to him and obey his voice; do not rebel against him, for he will not pardon your transgression, for my name is in him. “But if you carefully obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries.
Interest in angels is at an all-time low in our culture, and few people long to have an encounter with them. However, while seeing an angel would be a remarkable event, even the angels themselves are far more concerned that we heed God’s messages to us than they are that we see them face to face. We have in Scripture a message from the Lord delivered through the angels (Heb. 2:1–4)”Therefore we must pay much closer attention to what we have heard, lest we drift away from it. For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will.”
It is that message we must trust, follow, and obey.
