“For He will command His angels concerning you to guard you in all your ways,” reads Psalm 91:11. The writer of this Psalm is recognizing God’s ability to send down help to His creations through angelic means. The faithful are under the constant care and guidance of angels, and, given the words of Matthew 18:10, it is very possible that we each have our own specific guardian.
Since we know that bad things, at times, happen to all of us, we don’t know, exactly, in what way our angels guard us. But that doesn’t mean that they’re not helping! In the end, when we reach heaven, we may find that they safeguarded us from thousands of ills and troubles that we could have never imagined. Since God is all-knowing, we must assume that these angels keep us safe in exactly the ways we need most—no more, no less. Take comfort in knowing that God has assigned an angel to guard you in the best ways possible.
