…we would humbly entreat of Thee that we may each one be permitted to do some great service for Thee before we go hence: we do not mean great in the wisdom of our fellows, but let it be all that we can do. If we cannot build a house for Thee, yet we have set our hearts upon doing something; and if it be Thy will, direct our minds to what it shall be, lest our minds should not be Thy mind: but let not one of us be barren or unfruitful. If we have indeed been redeemed by the blood of Christ, may we reckon that we must live to Him; may the love of Christ constrain us, and may something come of our lives that shall be a blessing to the sons of men, ere we go hence.
