The key passage regarding guardian angels is found in Matthew 18:10 where Jesus said, “See that you do not look down on one of these little ones. For I tell you that their angels in heaven always see the face of my Father in heaven.” In the context, “these little ones” could either apply to those who believe in Him (v. 6) or it could refer to the little children (v. 3-5). The word “their” is a collective pronoun in the Greek and refers to the fact that believers are served by angels in general. These angels are pictured as “always” watching the face of God so as to hear His command to them to help a believer when it is needed.
Does each person has an angel assigned to him/her?
Scripture nowhere states that an angel is “assigned” to an individual. Angels were sent to individuals, but there is no mention of permanent assignment. However, God does use angels in ministering to His children on a continual basis (Genesis 28:12). And we have an even greater assurance that Jesus Christ Himself will never leave us (Psalms 121:4) or forsake us (Hebrews 13:5-6). His wall of protection is promised to His faithful children (Psalm 91).
There is no doubt that good angels serve in many capacities:
“And when he came to the den, he cried out with a lamenting voice to Daniel. The king spoke, saying to Daniel, “Daniel, servant of the living God, has your God, whom you serve continually, been able to deliver you from the lions?” Then Daniel said to the king, “O king, live forever! My God sent His angel and shut the lions’ mouths, so that they have not hurt me, because I was found innocent before Him; and also, O king, I have done no wrong before you” (Daniel 6:20-23 also 2 Kings 6:13-17),
2-Reveal God’s messages
“Which of the prophets did your fathers not persecute? And they killed those who foretold the coming of the Just One, of whom you now have become the betrayers and murderers, who have received the law by the direction of angels and have not kept it” (Acts 7:52-53 also Luke 1:11-20),
“But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit. And she will bring forth a Son, and you shall call His name Jesus, for He will save His people from their sins” (Matthew 1:20-21also Acts 8:26),
“And God heard the voice of the lad. Then the angel of God called to Hagar out of heaven, and said to her, “What ails you, Hagar? Fear not, for God has heard the voice of the lad where he is. Arise, lift up the lad and hold him with your hand, for I will make him a great nation.” Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water, and gave the lad a drink” (Genesis 21:17-19 also 1 Kings 19:5-7),
5-Minister to believers in general
“Are they not all ministering spirits sent forth to minister for those who will inherit salvation?” (Hebrews 1:14). In the Old Testament, the nation of Israel had the archangel (Michael) assigned to it (Daniel 10:21; 12:1).
