There are several Gospel scenes where the disciples clear children out of the way. Rebuking them, Jesus said, “Suffer little children to come to me.” And he said, “See that you despise none of them, because their angels in heaven always look upon the face of God.”
That is in Matthew’s Gospel, and he mentions angels in thirteen other places, but no where does he say each of us has his or her own Guardian Angel. The Bible doesn’t set out to satisfy our curiosity about such things. Many wonders are like presents we cannot open ahead of time As Paul told the people in Corinth, “Eye has not seen, ear has not heard, nor has it entered into the hearts of me the things God has planned for those who love him.
Still, angels are not a myth. It is fine for people to love them.. There is nothing wrong with praying, “O angel of God, my guardian dear, to whom his love commits me here.” Or, if you have the voice for it, there is nothing wrong with imitating Bing Crosby singing, “For you and I have an angel on high with nothing to do, but to give to me, and to give to you love forever true.”
The Bible tells us angels are real, and we might as well get them on our side.
