Guardian Angels With The Grace of God: Matthew 18:10.
Matthew 18:10
“Beware that you don’t look down on any of these little ones. For I tell you that in heaven their angels are always in the presence of my heavenly Father.
Angels that are swift as wind, rapidly doing Gods will, ministering judgment for God. In this passage, angels are the spirit creatures God sends according to the need of their service.
Angels are subject to the God- man Jesus Christ, not to man. We cannot summon them or order them to do our bidding even if it is something God wants to be done. Only God orders the angels, they are under his jurisdiction and control.
Do Believers Have Guardian Angels?
Sidewalks Chalk 
dear lord,
My Guardian Angel,
Thou come from heaven;
God has sent thee to take care of me.
Oh, shelter me under thy wings.
Lighten my path, direct my steps.
Do not leave me,
stay quite near me
and defend me against the spirit of evil.
But above all come to my help
in the struggle of my life.
I cannot be under this stress at this time in my life mentally and physically
Deliver my soul so that with thee it may praise,
love and contemplate the goodness of God
Please also a prayer for my relatives and friends that are under the care of their angels.
in this I pray
amen
dear lord,
very sad at the present but you know that already
please send your angels to help me
Evil, the Devil is so strong on Earth
his powers encompasses a person I love
please give him the strength not to be brought to evil and act disrespectful,
To My Guardian Angel:
