“For God has not given us the spirit of fear; but of power, and of love, and of a sound mind.” 2 Timothy 1:7
What a mercy it is naturally to have a sound mind! It is one of the greatest temporal blessings that God can bestow upon a man. It is far better than intellect, imagination, poetical gift, or reasoning power. And how wretched it is to have an unsound mind! A mind in the least degree diseased, eccentric, or in any way tainted with those delusive fancies which mar all comfort and often lead to the worst of consequences. But however great be the blessing of a healthy body, a healthy mind as much exceeds it in value as it is superior to it in nature. How you see men ruining themselves every day for lack of a sound mind! What disorder they bring upon their families, upon their property, and upon others also. What havoc and ruin from being crazed with some fancy or wild delusion!
To possess, then, the spirit of a sound mind is to have a sound judgment in the things of God—not to be drawn aside by every passing opinion—not to be allured by every novel doctrine—not to be charmed by every fresh device of the wicked one—not to be caught by every one of his flesh-pleasing snares—but to have that sobriety of judgment and holy wisdom in the things of God, with that fixedness of heart upon the Lord Jesus, and that solid experience of His Spirit and grace, as shall keep us from errors and delusions on the right hand and on the left.
Unless we have this spiritual sobriety—this ripe and matured judgment—and this firm establishment in the truth of God—we are almost sure to be drawn aside into some error or other. Satan will entangle us in a maze of confusion and error—he will beguile our minds with some of his subtle deceits.
But where there is a sound mind, there will be a sound faith—a sound hope—a sound love—a sound repentance—and a sound work of grace upon the heart from first to last. To have a sound mind is to have a mind deeply imbued and vitally impregnated with the truth of God. And [those who know the Truth] are the only people really possessed of soundness of mind—for they only take right and sound views of all things and all events, natural and spiritual, and have, as the apostle says, “the mind of Christ.”
