Of Men and Angels

We were made " a little lower than the angels",  Psalm 8:5
In what sense are we lower than the angels?, in strength ?
in power?,  in rank or authority?
Psalm 91:11...he will give his angels charge over you
to guard you in all your ways.
Psalm 103:20-21 stresses the strength of the angels, adding
that they are acting in direct response to the commandments
of God , listening to His very voice.i.e. in His authority !
The angels are personally concerned for us,
and have a knowledge of our actions and attitudes !
Luke 15:10....I tell you, there is joy in the presence 
of the angels of God, over one sinner who repents.

But, speaking of our state in the next world, the Lord Jesus tells us;-
we shall neither marry nor be given in marriage,
Neither can they die any more:
for they are equal to the angels;
and are the children of  God,
being the children of the resurrection...Luke 20:36 KJV
