For SINCERITY.
O Holy Lord, who requirest truth in the in∣ward parts, I humbly beseech thee to purge me from all hypocrisy and unsincerity. The heart, O Lord, is deceitful above all things, and my heart is deceitful above all hearts, O thou who searchest the heart, and reins, try me, and seek the ground of my heart, and suffer not any accursed thing to lurk within me but purify me even with fire, so thou con∣sume my dross. O Lord, I cannot deceive thee, but I may most easily deceive my self, I beseech thee let me not rest in any such deceit, but bring me to a sight and hatred of my most hidden corruptions, that I may not cherish any one darling lust, but make an utter de∣struction of every Amalekite; O suffer me not to speak peace to my self, when there is no peace, but grant I may judge of my self, as thou judgest of me, that I may never be at peace with my self, till I am at perfect peace with thee, and by purity of heart be qualified to see thee in thy Kingdom, through Jesus Christ.
