“Remember how unworthy you are to stand before him.  Remember how stained your garments are with sin and worldiness, how distracted your heart is with other thoughts and feelings, how poor the service is you are capable of rendering.  Remember how gloriously Jesus is served by the angels that excel in strength, that do His commandments, hearkening to the voice of His word.  And when you give yourselves to Him, or ask to be allowed to take your place among His servants, seek as you do so to be sprinkled with the blood of cleansing, own your personal unworthiness, and pray to be accepted through the merit of His sacrifice.”  (William G. Blaikie; 1820-1899)
