Answer

There is no person so thoroughly sanctified as not to fail and fall short in many things pertaining to relative duties. And to speak plainly, the corruptions of the holiest persons are as much discovered here as in anything else. And it is very common for conscience not only to charge these failures upon us, but to aggravate them to the utmost when God has made the separation. So that this is no more than what is usual and very common with persons in your case.
