4. Fourthly, When we do our services _unseasonably_, not only the grace and beauty of them is spoiled; but often are they rendered unprofitable. There are times to be observed, not only for the right management of common actions, but also for duties. What is Christian reproof, if it be not rightly suited to season and opportunity? The same may be said of other services. 5. Fifthly, Services are spoiled, when men set upon them _without resolutions of leaving their sins_. While they come with their ‘idols in their heart,’ and ‘the stumbling-block of their iniquity before their face, God will not be inquired of by them,’ Ezek. xiv. 3. He requires of those that present their services to him, that at least they should not affront him with direct purposes of continuing in their rebellions against him; nay, he expects from his servants that look for a blessing in their duties, that they come with their ‘hearts sprinkled from an evil conscience, and their bodies washed with pure water,’ Heb. x. 22. If they come to hear the word, they must ‘lay aside all filthiness, and superfluity of naughtiness,’ James i. 21; if they pray, they must ‘lift up pure hands,’ 1 Tim. ii. 8; if they come to the Lord’s Supper, they must eat that feast ‘with the unleavened bread of sincerity and truth,’ 1 Cor. v. 8. And albeit, he may accept the prayers of those that are so far convinced of their sins—though they be not yet sanctified—that they are willing to lay down their weapons, and are touched with a sense of legal repentance; for thus he heard Ahab, and regarded the humiliation of Nineveh: yet while men cleave to the love of their iniquity, and are not upon any terms of parting with their sins, God will not look to their services, but abhor them. For thus he declares himself, Isa. i. 11, ‘To what purpose is the multitude of your sacrifices? Bring no more vain oblations. I cannot away with them, it is iniquity, even the solemn meeting,—my soul hateth them, they are a trouble to me, I am weary to bear them: when you spread forth your hands, I will hide mine eyes from you; yea, when you make many prayers, I will not hear.’ The ground of all this is, that their heart was no way severed from the purposes of sinning, ‘Your hands are full of blood,’ ver. 15. Satan knowing this so well, he is willing that they engage in the services of God, if they will keep up their allegiance to him, and come with intentions to continue wicked still; for so, while he cannot prevent the actual performance of duty,—which yet notwithstanding he had rather do, because he knows not but God may by that means some time or other rescue these slaves of Satan out of his hand, —he makes their services nothing worth, and renders them abominable to God.
