Answer: The duty of Christians, after they have received the sacrament of the Lord’s Supper, is seriously to consider: How they have behaved themselves therein, and with what success₁; if they find quickening and comfort, to bless God for it₂, beg the continuance of it₃, watch against relapses₄, fulfil their vows₅, and encourage themselves to a frequent attendance on that ordinance₆: but if they find no present benefit, more exactly to review their preparation to, and carriage at, the sacrament₇; in both which, if they can approve themselves to God and their own consciences, they are to wait for the fruit of it in due time₈: but, if they see they have failed in either, they are to be humbled₉, and to attend upon it afterwards with more care and diligence₁₀.
