“What [true] prayer is. Prayer is a sincere, sensible, affectionate pouring out of the heart or soul to God, through Christ, in the strength and assistance of the Holy Spirit, for such things as God hath promised, or according to the Word, for the good of the church, with submission, in faith, to the will of God.”
“It is a SINCERE pouring out of the soul to God. Sincerity is such a grace as runs through all the graces of God in us, and through all the actings of a Christian, and hath the sway in them too, or else their actings are not any thing regarded of God, and so of and in prayer, of which particularly David speaks, when he mentions prayer. “I cried unto him,” the Lord “with my mouth, and he was extolled with my tongue. If I regard iniquity in my heart, the Lord will not hear” my prayer (Psa 66:17,18). Part of the exercise of prayer is sincerity, without which God looks not upon it as prayer in a good sense (Psa 16:1-4). Then “ye shall seek me and find me, when ye shall search for me with all your heart” (Jer 29:12-13). The want of this made the Lord reject their prayers in Hosea 7:14, where he saith, “They have not cried unto me with their heart,” that is, in sincerity, “when they howled upon their beds.” Sincerity was that which Christ commended in Nathaniel, when he was under the fig tree. “Behold, an Israelite indeed, in whom is no guile.” Probably this good man was pouring out of his soul to God in prayer under the fig tree, and that in a sincere and unfeigned spirit before the Lord. The prayer that hath this in it as one of the principal ingredients, is the prayer that God looks at. Thus, “The prayer of the upright is his delight” (Prov 15:8).
And why must sincerity be one of the essentials of prayer which is accepted of God, but because sincerity carries the soul in all simplicity to open its heart to God, and to tell him the case plainly, without equivocation; to condemn itself plainly, without dissembling; to cry to God heartily, without complimenting. Sincerity is the same in a corner alone, as it is before the face of the world. It knows not how to wear two vizards, one for an appearance before men, and another for a short snatch in a corner; but it must have God, and be with him in the duty of prayer. It is not lip-labour that it doth regard, for it is the heart that God looks at, and that which sincerity looks at, and that which prayer comes from, if it be that prayer which is accompanied with sincerity.”
