Love is the only weapon that can conquer the rebellious will and transform the soul from sin to holiness. And divine love does this only when it awakens responsive love in the sinner's breast. If love alone could save sinners, every prodigal son who has a mother would be drawn immediately from his husks to his home a reformed man. As a parent's love alone cannot save the dissolute son or fallen daughter, so God's love alone, though deep as hell and wide as the world, can save no soul from the guilt and love of sin. But love that awakens love in return is a magnet that draws men from the lowest depths near the very gates of perdition up to the highest heaven. The sinner whom love cannot save God cannot save, for salvation is absolutely impossible without responsive love, the first throb of which is the first pulsation of spiritual life. He is born again, born from above, for, behold, he loveth.
Herein is the secret of the rapid spread of the gospel going forth as an angel flying over all the world, not with a sword in her hand, but with a trumpet at her lips proclaiming God's love. Deny the vicarious atonement and we have an utterly impotent gospel. The churches which have tried this experiment have lost the light and warmth of evangelical truth, and have felt the chill, the frost, the death of mere naturalism. But wherever Christ crucified is preached as the Redeemer of the entire human race without one exception, and the Saviour of everyone who believes and receives the Holy Spirit, there is a quickening power which raises the dead to life and enkindles the fire of a quenchless zeal. Hence the cross of Christ becomes a live coal, which has touched myriads of dumb lips and made them eloquent to preach Christ crucified to all the world.
