The countless multitude of angels abide in the heavens, in the presence of God, fulfill God’s will and eternally glorify God.
Some of them are appointed by God to humans,
these are our guardian angels who protect people throughout their lives, from baptism until death, keep evil away from them and direct them to all truth and goodness.
If a person lives righteously, lives well, he will feel this himself. Think, dear brothers and sisters, how close angels are to us.
St. John of Kronstadt
