[ A] And the man of God, who was best acquainted with the heart among many thousands, both how euill it is, and how it is in the best manner to be looked vnto and preserued, he hath taught the same: that the seruant of God, who hath by his mercie his former life purged by the forgiuenes of his sinnes, must keepe it from new infections hereafter, by taking heede, and loo∣king to the same, according to Gods word.
This is plaine to them that haue experience in the Christian life, that men walking among so many snares of the diuell, baites of the world, and meeting with so infinite rebellions, and lusts of their owne hearts, as cannot be expressed, but as we finde them out by obseruing them, are not without [ B] continuall danger and hurt, if they be not acquainted with this holie watch and ward, that their knowledge may be as a light to them in this dark world, and their prouident care as a preseruatiue from the infection of sinne, which in all their dealings will meete with them: yea and (that I say nothing of them, who are without Christ in it) euen the beleeuers themselues (I meane) doe find much annoyance, and discomfort in their liues, which neither they needed to feare, neither should finde, if this counsell of the Prophet were pretious to them.
And to this end, that they who haue their hearts thus clensed, as I haue said, may continue them so still, they must know that it is no idle occupation thus [ C] to doe: but they must be content and glad to weane their hearts from many vnprofitable, and wandring thoughts and desires, which hold them here be∣low, and with the which others are caried away, as with a whirlewinde: and to season them with holie and heauenly meditations, as namely, of Gods goodnes, of their own frailties, and of their duties; that by the helpe of these, they may the better containe themselues within their bounds, and breake not foorth into dangerous euils. These are especiall helpes for the well or∣dering of their hearts still, who haue at any time brought them in order al∣readie: this being added, that their reading priuately, their hearing publike∣ly, with their oft and earnest prayers, and Christian conferences bee wisely, [ D] and at due times adioyned hereunto: of the which here is no fit place to giue any rules more particularly, because I haue appointed to direct men how to vse these, when I shall come to speake of the helpes and meanes which are to be vsed for the well gouerning of their hearts and liues, in the next treatise.
And thus the heart being renued and kept, it is easie to renounce euill, which otherwise is impossible: for euery one that listeth may see, both by Scripture, Psalm. 32.4, 5, 6. Hebr. 10.38. and by experience (notwithstanding our affections are strong, vnruly, and most hardly subdued) with what ease we may renounce and forsake them, and haue power ouer our will and ap∣petites, [ E] when our hearts bee thus renued and kept mastered: That is to say, when first they are purged, and our corrupt nature changed into a better by beleeuing the forgiuenes of our sins, and a partaking of the graces of Christ, and after, watched ouer and obserued that they continue so: who doth not see that the stubbornnest & wilfullest heart which hath most rebelled against good instruction and reformation, yet when it is thus looked vnto, will be ta∣med? And to speake more particularly (for the weake christians sake) when a
