When men live in order that they may retain the promise of eternal life, that they may attain eternal life hereafter, from fear lest they should forfeit the promise and not attain eternal life hereafter, they "live unto themselves." When men live because they already have as an actual possession, eternal life, and realize that it is eternal, they live from love, and not unto themselves but "_unto Him_." And God's plan is effective. "The love of Christ constraineth us" (2 Cor. 5:14), _it does constrain_. Hence, Jesus says, "if a man love me, _he will_ keep my words."--John 14:23. Again, "If God were your Father _ye would_ love me."--John 8:42. So important is this fact of the new motive power and its effectiveness, that the reader's attention will now be directed to the words of James Denny in "The Death of Christ" on this subject. That the reader may the better appreciate these words, his attention is first called to the estimates of Denny's great work by two of the leading religious editors of the world. The _Pittsburg Christian Advocate_: "To thoughtful students 'The Death of Christ' came as one of the most stirring books of the decade if not of the generation." The _New York Examiner_: "The most important contribution to the all-important doctrine of the atonement since the appearance of Dr. Dale's epoch-making book.... Exegetically considered, it is the most important book published within the memory of the younger generation of preachers." On the death of Christ for our sins (1 Cor. 15:3) being the motive power in the Christian life, and its being effective, Denny says: "The problem before us is to discover what it is in the death of Christ which gives it its power to generate such experience, to exercise on human hearts the constraining influence of which the apostle speaks; and this is precisely what we discover, in the inferential clause; 'so then all died.' This clause puts as plainly as it can be put the idea that His death was equivalent to the death of all; in other words, it was the death of all men which was died by Him."... "Their relation to God is not determined now _in the very least by sin or law_: it is determined by Christ, the propitiation, and by faith. The position of the believer is not that of one trembling at the judgment seat, or of one for whom everything remains somehow in a condition of suspense; it is that of one who has the assurance of a Divine love which has gone deeper than all his sins, and has taken on itself the _responsibility of them_, and _the responsibility of delivering him from them_."... "Take away the certainty of it and the New Testament temper expires. Joy in this certainty is not presumption; on the contrary, it is joy in the Lord, and such joy is the Christian's strength. It is the impulse and the hope of sanctification; and to deprecate it, and the assurance from which it springs, is no true evangelical humility, but a failure to
