3 For this reason the Lord also said, “Let your light so shine before men, that they may see your good deeds, and glorify your Father who is in heaven.” And, “Take heed to yourselves, lest perchance your hearts be overcharged with surfeiting, and drunkenness, and worldly cares.” And, “Let your loins be girded about, and your lamps burning, and you like men that wait for their Lord, when He returns from the wedding, that when He comes and knocks, they may open to Him.
Blessed is that servant whom his Lord, when He comes, shall find so doing.” And again, “The servant who knows his Lord's will, and does it not, shall be beaten with many stripes.” And, “Why call me, Lord, Lord, and do not the things which I say?” And again, “But if the servant say in his heart, The Lord delays, and begin to beat his fellow-servants, and to eat, and drink, and to be drunken, his Lord will come in a day on which he does not expect Him, and shall cut him in sunder, and appoint his portion with the hypocrites.” All such passages demonstrate the independent will of man, and at the same time the counsel which God conveys to him, by which He exhorts us to submit ourselves to Him, and seeks to turn us away from [the sin of] unbelief against Him, without, however, in any way coercing us.
