Angels are heavenly beings that are messengers of God. They are often depicted in scripture as dressed in white with wings.
There are differeny types of angels. Angels of the lord are assigned to transmit God’s message. In mathew 1:20, God sent an angel to warn a joseph in his dream not to abandon Mary after he realised she bore a child that was not his. God sent an angel to tell Abraham that he would have many descendents like the stars in the sky after he offered to sacrifice his only son to God.(Gen 22:15) Just as God has angels, the devil has angels too.
In the book of mathew 25:41, Jesus said at judgement day, he would seperate the righteous from the rest of the people and that the later would be cast into eternal fire reserved for the devil and his angels. In Rev. 12:7, the bible says the devil and his angels were thrown down to earth after they were defeated in heaven by Michael and other angels. Michael was the chief angel.
Angel are not only messengers. They are known to perform other functions too. They can be helpers. In Daniel 6:22, God sent angels to help close the mouth of the lion so they could not kill daniel while he was in the lion’s den. Angels came to help Jesus after he was tempted by the devil ( mathew 4:11 ) . Angels can be assigned to kill. In exodus 12:23, God sent the angels of death to kill the Egyptians sparing the lives of the Israelites. Again in the book of Isaiah 37:36, an angel of the Lord went to the assyrian camp and killed 185000 soldiers.
Angels can be known as guides. In numbers 20:10, God sent an angel to lead the children of Israel out of Egypt after they cried to him for help. Finally, angels are famous for their strength. In psalm 103:20, the psalmist say “bless the Lord, all of you his angels that excel in strength and …. The good news translation renders it as ” praise the Lord, you strong and mighty angels who obey his commands.”
