In the knowledge of ourselves, in reference to our eternal condition, doth much of our wisdom consist. There is not any thing wherein, in this depraved condition of nature, we are more concerned than sin; without a knowledge of that, we know not ourselves. “Fools make a mock of sin.” A true saving knowledge of sin is to be had only in the Lord Christ: in him may we see the desert of our iniquities, and their pollution, which could not be borne or expiated but by his blood; neither is there any wholesome view of these but in Christ. In him and his cross is discovered our universal impotency, either of atoning God’s justice or living up to his will. The death of sin is procured by, and discovered in, the death of Christ; as also the manifestation of the riches of God’s grace in the pardoning thereof. A real and experimental acquaintance, as to ourselves, with all which, is our wisdom; and it is that which is of more value than all the wisdom of the world.
