Conclusion of the first part of the epistle
As far as was possible, and could be done with perspicuity, I cherish the hope that, according to my desire, I have omitted none of those things at present [demanding consideration], which bear upon your salvation. For if I should write to you about things future, you would not understand, because such knowledge is hid in parables. These things then are so.
