Thine own right hand can save thee - It is the prerogative of God alone to save the human soul. Nothing less than unlimited power, exerted under the direction and impulse of unbounded mercy, can save a sinner. This is most clearly asserted in this speech of Jehovah: When thou canst extend an arm like God, i.e., an uncontrollable power - when thou canst arm thyself with the lightning of heaven, and thunder with a voice like God - when thou canst deck thyself with the ineffable glory, beauty, and splendor of the supreme majesty of Jehovah - when thou canst dispense thy judgments over all the earth, to abase the proud, and tread down the wicked - when thou canst as having the keys of hell and death, blend the high and the low in the dust together; then I will acknowledge to thee that thy own right hand can save thee. In other words: Salvation belongeth unto the Lord; no man can save his own soul by works of righteousness which he has done, is doing, or can possibly do, to all eternity. Without Jesus every human spirit must have perished everlastingly. Glory be to God for his unspeakable gift!

Objection 1: It would seem that there is hope in the damned. For the devil is damned and prince of the damned, according to Mat. 25:41: "Depart . . . you cursed, into everlasting fire, which was prepared for the devil and his angels." But the devil has hope, according to Job 40:28, "Behold his hope shall fail him." Therefore it seems that the damned have hope. Objection 2: Further, just as faith is either living or dead, so is hope. But lifeless faith can be in the devils and the damned, according …

On the Interior Man
The interior man is the rational soul; in the apostle: have in your hearts, in the interior man, Christ through faith. [Eph. 3:16] His head is Christ; in the apostle: the head of the man is Christ. [I Cor. 11:3] The crown of the head is the height of righteousness; in Solomon: for the crown of your head has received the crown of grace. The same in a bad part: the crown of hairs having walked about in their own delights, that is, in the height of iniquity. [Prov. 4:9; Ps. 67(68):22(21)] The hair is …
