1. First, _By distracting or disturbing our thoughts_. This is a usual policy of Satan. Those fowls which came down upon Abraham’s sacrifice are supposed by learned expositors to signify those means and ways by which the devil doth disorder and trouble our thoughts in religious services, Gen. xv. 12. And Christ himself compares the devil stealing our thoughts from duty, to the ‘fowls of the air,’ that gather up the seed as soon as it is sown, Mat. xiii. 4. There are many reasons that may persuade us that this is one of his masterpieces of policy. As (l.) in that the business of distraction is oft easily done. Our thoughts do not naturally delight in spiritual things, because of their depravement; neither can they easily brook to be pent in or confined so strictly as the nature of such employments doth require; so that there is a kind of preternatural force upon our thoughts, when they are religiously employed; which as it is in itself laborious, like the stopping of a stream, or driving Jordan back, so upon the least relaxing of the spring, that must bend our thoughts heavenward, they incline to their natural bend and current; as a stone rolled up a hill, hath a _renitentia_, a striving against the hand that forceth it, and when that force slackens it goes downward. How easily then is it for Satan to set our thoughts off our work! If we slacken our care never so little, they recoil and tend to their old bias; and how easy is it for him to take off our hand, when it is so much in his power to inject thoughts and motions into our hearts, or to present objects to our eyes, or sounds to our ears, which by a natural force raiseth up our apprehension to act, for in such cases _non possumus non cogitare_; we cannot restrain the act of thinking, and not without great heedfulness can we restrain the pursuit of those thinkings and imaginations. (2.) Satan can also do it insensibly. Our distractions or rovings of thoughts creep and steal upon us silently, we no more know of it when they begin than when we begin to sleep, or when we begin to wander in a journey, where oft we do not take ourselves to be out of the way, till we come to some remarkable turning. (3.) And when he prevails to divide our thoughts from our duty, he always makes great advantage, for thus he hinders at least the comfort and profit of ordinances. While we are busied to look to our hearts, much of the duty goeth by, and we are but as those that in public assemblies are employed to see to the order and silence of others, who can be scarce at leisure to attend for their own advantage. Besides, much of the sweetness of ordinances are abated by the very trouble of our attendance. When we are put to it, as Abraham was, to be still driving away those fowls that come down upon our sacrifice, the very toil will eat out and eclipse much of the comfort. Thus also he at least provides matter to object against the sincerity of the servants of God; and will assuredly find a time to
