7. The last means is, to choose some prudent, faithful guide and counsellor for your soul,[35] to open those cases to which are not fit for all to know, and to resolve and advise you in cases that are too hard for you: not to lead you blindfold after the interest of any seduced or ambitious men, nor to engage you to his singular conceits, against the Scripture or the church of God; but to be to your soul, as a physician to your body, or a lawyer to your estates, to help you where they are wiser than you, and where you need their helps.

That in all this you may be sincere, and not deceived by a hypocritical change, be sure that God be all your confidence, and all your hopes be placed in heaven; and that there be no secret reserve in your hearts, for the world and flesh; and that you divide not your hearts between God and the things below, nor take up with the religion of a hypocrite, which giveth God what the flesh can spare. When the devil cannot keep you from a change and reformation, he will seek to deceive you with a superficial change and half reformation, which goeth not to the root, nor doth recover the heart to God, nor deliver it entirely to him.
