How then, it may be asked, can the conduct of David be accounted for? The answer is simple enough--on the ground of original sin. Like the rest of us, he was born with proclivities to evil--to irregular desires craving unlawful indulgence. When divine grace takes possession of the heart it does not annihilate sinful tendencies, but overcomes them. It brings considerations to bear on the understanding, the conscience, and the heart, that incline and enable one to resist the solicitations of evil, and to yield one's self to the law of God. It turns this into a habit of the life. It gives one a sense of great peace and happiness in resisting the motions of sin, and doing the will of God. It makes it the deliberate purpose and desire of one's heart to be holy; it inspires one with the prayer, "Oh that my ways were directed to keep Thy statutes! Then shall I not be ashamed, when I have respect unto all Thy commandments." But, meanwhile, the cravings of the old nature are not wholly destroyed. "The flesh lusteth against the spirit, and the spirit lusteth against the flesh." It is as if two armies were in collision. The Christian who naturally has a tendency to sensuality may feel the craving for sinful gratification even when the general bent of his nature is in favour of full compliance with the will of God. In some natures, especially strong natures, both the old man and the new possess unusual vehemence; the rebellious energisings of the old are held in check by the still more resolute vigour of the new; but if it so happen that the opposition of the new man to the old is relaxed or abated, then the outbreak of corruption will probably be on a fearful scale. Thus it was in David's nature. The sensual craving, the law of sin in his members, was strong; but the law of grace, inclining him to give himself up to the will of God, was stronger, and usually kept him right. There was an extraordinary activity and energy of character about him; he never did things slowly, tremblingly, timidly; the wellsprings of life were full, and gushed out in copious currents; in whatever direction they might flow, they were sure to flow with power. But at this time the energy of the new nature was suffering a sad abatement; the considerations that should have led him to conform to God's law had lost much of their usual power. Fellowship with the Fountain of life was interrupted; the old nature found itself free from its habitual restraint, and its stream came out with the vehemence of a liberated torrent. It would be quite unfair to judge David on this occasion as if he had been one of those feeble creatures who, as they seldom rise to the heights of excellence, seldom sink to the depths of daring sin.
