Having tried, we must hold fast [to the truth] (I Thes. 5:21), upon [the penalty of] the loss of a crown (Rev. 3:11); we must not let go for all the fleabitings of the present afflictions, etc. Having bought truth dear, we must not sell it cheap, not the least grain of it for the whole world; no, not for the saving of souls, though our own most precious; least of all for the bitter sweetening of a little vanishing pleasure.
