DO WE EACH HAVE AN INDIVIDUAL GUARDIAN ANGEL?

In Matthew 18:10 Jesus tells us that the angels of children always see the face of God and, in Hebrews 1:14, we learn that the angels serve those who will inherit salvation. Even before that, Psalm 91:11 advises that God commands his angels to guard us; however, in Revelations 22:8-9, we are reminded to be careful not to pray to or worship angels. I can find no evidence in the Bible that we have individual guardian angels. Perhaps the risk of having guardian angels would be a tendency to develop a spiritual relationship with them; a relation that must be reserved for God.
