From Jonathan Edwards's "Advice to Young Converts":

Under special difficulties, or when in great need of or great longings after particular mercies for your self or others, set apart a day of secret fasting and prayer alone. Let the day be spent not only in petitions for the mercies you desired, but in searching your heart, and looking over your past life, and confessing your sins before God, not as practiced in public prayer, but by a very particular rehearsal before God. Include the sins of your past life from your childhood up until now, both before and after conversion, with particular circumstances and aggravations. Also be very particular and as thorough as possible, spreading all  the abominations of your heart before him.
