(2.) Secondly, Besides this he hath an _experimental knowledge_; which is the improvement of that natural stock, by further acquisitions and attainments. And indeed Satan had very high advantages for an increase of knowledge. He had a great stock to begin withal; he hath had fit and suitable objects to work upon in his contemplations, so that by comparing things with things in so large a field of variety, and that for so many years together, it cannot be but that he should be grown more experienced and subtle than he was at first; and the Scripture doth fairly countenance this supposition, by telling us of his devices, 2 Cor. ii. 11; of his wiles, Eph. vi. 11; and of his depths, Rev. ii. 24.[94] All which phrases imply that Satan hath so studied the point of temptation, that he hath now, from long experience and observation, digested it into an art and method, and that with such exactness that it is become a mystery and a depth, much covered and concealed from the notice and observation of men. (3.) Thirdly, To both the former may be added another knowledge, which because it is from another spring, I may call it an _accessory knowledge_, consisting in occasional discoveries made to him, either when God is pleased to make known so much of his mind and purpose, as he employs him, as an instrument or servant, to execute, as he did in the case of Job and Ahab; or when he informs himself from the Scriptures, or catcheth hints of knowledge from the church and the ordinances thereof. If good angels have an increase of knowledge this way, as is evident they have, ‘for to principalities and powers in heavenly places is made known by the church the manifold wisdom of God,’ Eph. iii. 10, we cannot but imagine that Satan hath some addition of knowledge from such discoveries. While we are upon this point, it will be necessary to offer some satisfaction to two questions. _Quest._ 1. First, Whether Satan knows our thoughts? _Ans._ 1. It is undoubtedly God’s prerogative to know the thoughts. He knows them intuitively, which is beyond the power of any creature: Jer. xvii. 9, ‘Who can know it?’ This is a challenge to all, implying the utter impossibility of it to any but to God alone; ‘I the Lord search the heart;’ he knows the most inward thoughts: Rev. ii. 23, ‘I am he which searcheth the reins, and the heart;’ he knows them evidently and certainly: Heb. iv. 13, ‘All things are naked and open[95] before him with whom we have to do.’ Those secret thinkings and intendments which are hid from others, and which we ourselves cannot distinctly read, because of their secret intricacy or confusedness, yet the very inside and outside of them are uncased, cut up and anatomised by his eye; in all which expressions God is careful to reserve this to himself, ‘I the Lord do it,’ or ‘I am he, &c., that searcheth;’ and signifies that none else is able to do the like.
