Verses 1-4. There is revelation that the impure truth of the natural man is to be devoted to the Lord through truth proceeding from good; that it is to be prepared for purification; that it must be acknowledged to come from the Lord and must, therefore, be conjoined with good in the course of regeneration.

Verses 5-10. All falsity and evil are to be separated from the truth; and through the influence of truth from good, purification shall be effected by the truths of the Word; and further particulars are then given concerning this process.

Verses 9, 11-22. Several cases are given in which this law of purification is to be applied; and in short, every one who does not apply this law by the confession that of himself he is nothing but evil, must remain in a state of impurity and be separated from the church.
