As Satan slanders Christ to us, so he slanders us to ourselves. If thou be not so much as smoking flax, then why dost thou not renounce thy interest in Christ and disclaim the covenant of grace? This thou darest not do. Why dost thou not give up thyself wholly to other enjoyments? This thy spirit will not suffer thee.
The devil is a great student in divinity and makes no other use of his Scripture knowledge than may serve his turn by sophistry to do the Christian a mischief, either by drawing him into sin or into despair for sinning, like some wrangling barrister who gets what skill he can in the law merely to make him the more able to put honest men to trouble by his vexatious suit.
The Christian wrestles not with his naked corruptions, but with Satan in them. Were there no devil, yet we should have our hands full in resisting the corruptions of our own hearts, but the access of this enemy makes the battle more terrible because he heads them, who is a captain so skillful and experienced. Our sin is the engine, Satan is the engineer; lust the bait, Satan the angler. When a soul is enticed by his own lusts, he is said to be tempted (James 1:14) because both Satan and our own lusts concur to the completing the sin.
Watchful and suspicious ought we to be in spiritual concernments. We should study and be acquainted with Satan's wiles and policy. The apostle takes it for granted that Christians are not ignorant of his devices (2 Cor. 2:11). "The serpent's eye," as one saith, "would do well in the dove's head." The devil is a cunning pirate; he puts out false colors and ordinarily comes up to the Christian in the disguise of a friend.
God had but one Son without corruption, but He had none without temptation (Heb. 2:17–18). Pirates make the fiercest assaults upon those vessels that are most richly laden; so doth Satan upon those souls that are most richly laden with treasures of grace, with the riches of glory. Pirates let empty vessels pass and repass without assaulting them; so doth Satan let souls that are empty of God, of Christ, of the Spirit, of grace pass and repass without tempting or assaulting of them.
Satan's masterpiece is first to work Christians to blot and blur their evidences for glory by committing this or that heinous sin, and then his next work is to rob them of their evidences for glory that so, though at the long run they may get safe to heaven, that yet Jacob-like they may go halting and mourning to their graves. Satan knows that whilst a Christian's evidences are bright and shining, a Christian is temptation proof. Satan may tempt him, but he cannot conquer him; he may assault him, but he cannot vanquish him.
In handling this point of Satan's subtlety, we shall consider him in his two main designs and therein show you his wiles and policies. His first main design is to draw into sin. The second is to accuse, vex, and trouble the saint for sin.
Many have yielded to go a mile with Satan that never intended to go two, but when once on the way have been allured further and further, till at last they know not how to leave his company.
He bears you the greatest malice who are engaged to do him the greatest mischief. He has found, by experience, that to "smite the shepherd" is the most effectual means to "scatter the flock." You therefore shall have his most subtle insinuations, incessant solicitations, and violent assaults. Reformed Pastor
In every good work, we must depend on the Lord. If anyone rises so that he may give the time which he takes from sleep to prayer and meditation, let him be sure that Satan will try to put obstacles in the way.
Satan will first draw you to sit with the drunkard, and then to sip with the drunkard, and then at last to be drunk with the drunkard. He will first draw you to be unclean in your thoughts, and then to be unclean in your looks, and then to be unclean in your words, and at last to be unclean in your practices.Precious Remedies Against Satan's Devices
