Luke 2:10-11 FNV
Angels were heralds of the new-born Saviour, but they were only sent to some poor, humble, pious, industrious shepherds, who were in the business of their calling, keeping watch over their flock.
We are not out of the way of Divine visits, when we are employed in an honest calling, and abide with God in it.
