To all that love the Lord Jesus Christ in sincerity and in truth; such as feel the plague of their own hearts, and know their own sore; such as are acquainted with Satan's temptations, and are sick of themselves; sick of this ungodly world; sick of carnal, notional professors, and of the awful errors that abound in our day; and those who in heart are simply seeking the blessed Savior of sinners, is this little book sent out. Rusk remarks on Isaiah 40:20 for the spiritually exercised reader who will find that the tongue of the just is as choice silver.
