I look upon prayer-meetings as the most profitable exercises (excepting the public preaching) in which Christians can engage. They have a direct tendency to kill a worldly, trifling spirit, and to draw down a Divine blessing upon all our concerns, compose differences, and enkindle (at least maintain) the flames of Divine love amongst brethren.
