Camp Meeting Song Lyrics Artifact

Camp-meetings with thy presence crown,
And show't O Lord, they blessings down;
Fill every heard with holy zeal,
And all thy righteousness reveal,
O'er all our hosts do thou preside,
And all our various movements guide;
The praying companies attend,
And show thyself the sinner's friend.
Pour cut the Spirit on thy sons,
And visit thy anointed ones;
May every virgin trim her lamp,
And glory rest upon our camp.
May prayer and praise united rise
Like holy incense to the skies;
In all our hosts display thy power!
May souls be born again this hour!
