About : Angels
The Bible teaches us a good amount about angels & demons. "Angels" or "angel" appears 109 times in the Old Testament & 180 times in the New Testament. Revelation 5: 11 speaks of Apostle John seeing 10,000 times 10,000 angels & thousands of thousands. Base on that, we know there are over 100,000,000 angels. In Revelations 12:4 its speaks of the "stars of heaven" which is believed by most to be a reference to the fallen angels who were cast from Heaven, along side Lucifer. There was 1/3 of the angels that were cast from heaven. These fallen angels became "demons". Doing the math, we can estimate, give or take, that there was once 150,000,000 total angels. Since one third of them were cast from Heaven to the earth, that would leave 100,000,000 angels & 50,000,000 demons. In Mathew 26:53 Jesus spoke to Peter and told him He (Jesus) could have called twelve legions (72,000) angels to his defense if he so desired. Jesus met a demon possessed man who, when asked of its name, it responded "legion" (Mark 5:9). Because this man was filled with many demons, it simply referred to its name as a group. The Scripture definition for "possessed" means "to have a demon". Though some do, many don't act as if they are possessed. It is possible for someone to be partially controlled by a demon and still appear to be a normal person.
Are angels physical or non-physical beings?
Demons never appeared in bodily form in the Scripture, but actually appeared inside of a human host. Jesus speaks of meeting two people who are demon possessed in Mathew 8:28 thru 31. It is shown that the demons, or "devils" feared Jesus. They asked if He has come to torment them before their time. This teaches that demons (fallen angels) know that they have a limited time before judgment. In Matthew 25:41 the Scripture speaks of the Devil (formally known as Lucifer) and his angels will be tormented for eternity for turning away from God. Jesus allowed the demons to enter into swine (pigs) as part of a request and He allowed it. In that, we learn demons can enter into animal bodies and possess them as well. Unlike demons, however, angels sent by God did appear in bodily (physical) form a few times in the Bible. They were sometimes visible to the human senses and other times they were not. Normally, angels cannot be seen/heard/felt ect. by the human senses. In 2nd Kings 6:15 thru 17, the prophet Elisha asked God to open the eyes of his servants so they may see the horses & chariots of fire going thru the city. In Genesis 18:1 thru 2. Abraham saw three angels who appeared as regular men from his tent. Looking into this further, we can look to Hebrews 13:2 which talks about coming into contact with angels without knowing it. It warns us to be kind to strangers for we may not know if they are angels or not. If we were to ever meet an angel, chances are, we would not even know it! The Bible states that some believers have associated with angels unaware to it happening. If you were to meet an angel, you would not be able to distinguish him from any other human man. The angels do have a physical body. It is somewhat difficult to understand how a spiritual being could appear in a physical body, but we know they can and do. Jesus physically appeared in the furnace with Shadrach, Meshach & Abed-Nego in Daniel's time. How is this possible? The Messiah has not been physically born into the world yet so He appeared as the angel of the Lord. Psalms 90:4 reads "For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.".
What is an angel's purpose?
Hebrews 1:14 teaches that angels are set forth by God to serve the Saints. Each believer/follower in/of Jesus Christ has their own guardian angel assigned to watch over them. Matthew 18:10 reads "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 which is in heaven". Each of our angels watches the face of God and waits for the Lord's next command. In Psalms 34:7 speaks of the angels protecting all those who fear God. We are not to be looking for angels or doing anything to please them. We are to please God and only God. Angels are sent by God to minister to us so we may give ourselves to the Lord to serve Him. They are meant for our protection on a journey upstream.
Do angels eat?
In Psalms 78:25 it reads "Man did eat angel's food: he sent them meat to the full.", so, evidently, angels did & do eat. Jesus in His resurrected body ate and drank like a normal man with His disciples. The Bible says that every saint will receive a body that is like the Lord's at His Rapture(the first resurrection).
Communication with angels.
There is no Scripture that commands us to seek communication with the angels nor for us to look for them. It states that Jesus is the only mediator between God (the Father) & mankind. Revelation 4:11 tells us that all things were created for God's own pleasure. This should be our desire as followers of Christ... To please God. Much of "commercial" Christianity is based around centering ourselves. The Gospel does not teach us to be worried about our physical life, but to rather let it die. This is in the sense that we are dead to our flesh and denying ourselves. In Matthew 16:24 Jesus spoke of denying one's self by taking the cross up and following Him.We are to focus on pleasing God not His creations.
The point of the angels in the Bible.
"Angels" or "angel" appears 109 times in the Old Testament & 180 times in the New Testament...This is to encourage us. God cares about us as His children. He wants us to cast our cares and worries upon Him. He has His angels watch over us and care for us. When we pray, God listens. God only expects us to pray about everything, good and bad, and to wait upon the Lord. It is our responsibility to pray and to leave the rest up to God, to trust Him completely. "Ye are of God, little children, & have overcome them: because greater is He that is in you, than he that is in the world." (1 John 4:4)
