If one is a Christian they most assuredly believe in Angels! They are mentioned over 200 times in the bible.Angels are often used by God to make intervention on behalf of his children.
Jesus had Angels minister to him after being tempted in the wilderness……
“Then saith Jesus unto him,get thee hence,satan:for it is written,thou shalt worship the Lord thy God,and him only shalt thou serve.Then the devil leaveth him,and,behold,Angels came and ministered unto him”.(Matthew 4:10,11).
It was an Angel that was sent on Daniels behalf to shut the mouths of the lions.
“My God hath sent his Angel,and hath shut the lions’ mouths,that they have not hurt me:forasmuch as before him innocency was found in me;and also before thee,O King,have I done no hurt.Then was the King exceeding glad for him,and commanded that they should take Daniel up out of the den.So Daniel was taken up out of the den,and no manner of hurt was found upon him,because he believed in his God”.(Daniel 6:22,23).
My favorite bible story of an Angel is when Balaam’s donkey saw the Angel of the Lord and then God opened the mouth of the donkey to speak!
“And when the ass saw the Angel of the Lord,she fell down under Balaam:and Balaam’s anger was kindled,and he smote the ass with a staff.And the Lord opened the mouth of the ass,and she said unto Balaam,what have I done unto thee,that thou hast smitten me these three times?
And Balaam said unto the ass,because thou hast mocked me:I would there were a sword in mine hand,for now would I kill thee.And the ass said unto Balaam,Am not I thine ass,upon which thou hast ridden ever since I was wont to do so unto thee? And he said,nay.Then the Lord opened the eyes of Balaam,and he saw the Angel of the Lord standing in the way,and his sword drawn in his hand:and he bowed down his head,and fell flat on his face.And the Angel of the Lord said unto him,wherefore hast thou smitten thine ass these three times? Behold,I went out to withstand thee,because thy way is perverse before me.
And the ass saw me,and turned from me these three times:unless she had turned from me,surely now also I had slain thee,and saved her alive”.(Numbers 22:27-33).
Then there are Angels who bring healing as in the pool of Bethesda.(John 5:1-14)
Perhaps even you have had an encounter with an Angel?
“Be not forgetful to entertain strangers:for thereby some have entertained Angels unawares”.(Hebrews 13:2).
