6. I say, of _the heart_. For neither does religion consist in _orthodoxy_ or _right opinions_; which altho’ they are not properly outward things, are not in the heart, but the understanding. A man may be orthodox in every point; he may not only espouse right opinions, but zealously defend them against all opposers: he may think justly concerning the incarnation of our Lord, concerning the ever blessed Trinity, and every other doctrine, contained in the oracles of God: He may assent to all the three creeds: that called the apostles’, the _Nicene_, and the _Athanasian_: and yet ’tis possible, he may have no religion at all, no more than a _Jew_, _Turk_, or _Pagan_. He may be almost as orthodox as――――the devil; (tho’ indeed, not altogether. For every man errs in something; whereas we can’t well conceive him to hold any erroneous opinion) and may all the while be as great a stranger as he, to the religion of the heart. 7. This alone is religion, truly so call’d: this alone is in the sight of God of great price. The apostle sums it all up in three particulars, _righteousness, and peace, and joy in the Holy Ghost_. And first, _righteousness_. We cannot be at a loss concerning this, if we remember the words of our Lord describing the two grand branches thereof, on which _hang all the law and the prophets. Thou shalt love the Lord thy God with all thy heart, and with all thy mind, and with all thy soul, and with all thy strength.[22] This is the first and great commandment_, the first and great branch of Christian righteousness. Thou shalt delight thyself in the Lord thy God; thou shalt seek and find all happiness in him. He shall be _thy shield, and thy exceeding great reward_, in time and in eternity. All thy bones shall say, _Whom have I in heaven but thee? And there is none upon earth that I desire beside thee!_ Thou shalt hear, and fulfil his word who saith, _My son, give me thy heart_. And having given him thy heart, thy inmost soul, to reign there without a rival, thou mayest well cry out, in the fulness of thy heart, _I will love thee, O Lord, my strength. The Lord is my strong rock and my defence: my Saviour, my God, and my might, in whom I will trust; my buckler, the horn also of my salvation, and my refuge._
