2:1-10 Sin is the death of the soul. A man dead in trespasses and sins has no desire for spiritual pleasures. When we look upon a corpse, it gives an awful feeling. A never-dying spirit is now fled, and has left nothing but the ruins of a man. But if we viewed things aright, we should be far more affected by the thought of a dead soul, a lost, fallen spirit. A state of sin is a state of conformity to this world. Wicked men are slaves to Satan. Satan is the author of that proud, carnal disposition which there is in ungodly men; he rules in the hearts of men. From Scripture it is clear, that whether men have been most prone to sensual or to spiritual wickedness, all men, being naturally children of disobedience, are also by nature children of wrath. What reason have sinners, then, to seek earnestly for that grace which will make them, of children of wrath, children of God and heirs of glory! God's eternal love or good-will toward his creatures, is the fountain whence all his mercies flow to us; and that love of God is great love, and that mercy is rich mercy. And every converted sinner is a saved sinner; delivered from sin and wrath. The grace that saves is the free, undeserved goodness and favour of God; and he saves, not by the works of the law, but through faith in Christ Jesus. Grace in the soul is a new life in the soul. A regenerated sinner becomes a living soul; he lives a life of holiness, being born of God: he lives, being delivered from the guilt of sin, by pardoning and justifying grace. Sinners roll themselves in the dust; sanctified souls sit in heavenly places, are raised above this world, by Christ's grace. The goodness of God in converting and saving sinners heretofore, encourages others in after-time, to hope in his grace and mercy. Our faith, our conversion, and our eternal salvation, are not of works, lest any man should boast. These things are not brought to pass by any thing done by us, therefore all boasting is shut out. All is the free gift of God, and the effect of being quickened by his power. It was his purpose, to which he prepared us, by blessing us with the knowledge of his will, and his Holy Spirit producing such a change in us, that we should glorify God by our good conversation, and perseverance in holiness. None can from Scripture abuse this doctrine, or accuse it of any tendency to evil. All who do so, are without excuse.
2. the course of this world—the career (literally, "the age," compare Ga 1:4), or present system of this world (1Co 2:6, 12; 3:18, 19, as opposed to "the world to come"): alien from God, and lying in the wicked one (1Jo 5:19). "The age" (which is something more external and ethical) regulates "the world" (which is something more external).
the prince of the power of the air—the unseen God who lies underneath guiding "the course of this world" (2Co 4:4); ranging through the air around us: compare Mr 4:4, "fowls of the air" (Greek, "heaven") that is, (Eph 2:15), "Satan" and his demons. Compare Eph 6:12; Joh 12:31. Christ's ascension seems to have cast Satan out of heaven (Re 12:5, 9, 10, 12, 13), where he had been heretofore the accuser of the brethren (Job 1:6-11). No longer able to accuse in heaven those justified by Christ, the ascended Saviour (Ro 8:33, 34), he assails them on earth with all trials and temptations; and "we live in an atmosphere poisonous and impregnated with deadly elements. But a mighty purification of the air will be effected by Christ's coming" [Auberlen], for Satan shall be bound (Re 12:12, 13, 15, 17; 20:2, 3). "The power" is here used collectively for the "powers of the air"; in apposition with which "powers" stand the "spirits," comprehended in the singular, "the spirit," taken also collectively: the aggregate of the "seducing spirits" (1Ti 4:1) which "work now (still; not merely, as in your case, 'in time past') in the sons of disobedience" (a Hebraism: men who are not merely by accident disobedient, but who are essentially sons of disobedience itself: compare Mt 3:7), and of which Satan is here declared to be "the prince." The Greek does not allow "the spirit" to refer to Satan, "the prince" himself, but to "the powers of the air" of which he is prince. The powers of the air are the embodiment of that evil "spirit" which is the ruling principle of unbelievers, especially the heathen (Ac 26:18), as opposed to the spirit of the children of God (Lu 4:33). The potency of that "spirit" is shown in the "disobedience" of the former. Compare De 32:20, "children in whom is no faith" (Isa 30:9; 57:4). They disobey the Gospel both in faith and practice (2Th 1:8; 2Co 2:12).
