"This is what salvation is all about: restoring former rebels to their rightful place as obedient servants of God (Rom. 6:16-17).
Man's sin, like Lucifer's, constituted cosmic rebellion. The penalty was death (Gen. 2:17). God's program of redemption is calculated not chiefly to dismiss that penalty (though this it certainly does), but rather to restore man to his rightful place as an obedient son called to exercise dominion in the earth (Ps. 8:4-8; Eph. 1:3, 10, 18-23). Keeping sinners out of hell is merely the by-product of God's plan to reinstall covenant-keeping man in his original task as His vicegerent in the earth (Gen. 1:27-28). This is why the godly are placed in the earth: to extend His kingdom and His righteous reign throughout the whole earth (Rev. 2:26-27)...
...A salvation that merely keeps souls out of hell is, as Rushdoony notes, fire insurance; it is not biblical salvation."
