Answer Third. Inquire in what posture thy heart stands to the word of command. The promise, may be, is sweet to thy palate. This thou rollest like a lump of sugar under thy tongue, but are not thy teeth set against the command as if it were gall and worm¬wood? Thou smilest on the promise, but when put in mind of thy duty to the command, then haply thy countenance is changed, and a frown sits on thy brow, as if God were some austere master that breaks his servants’ backs with heavy burdens. And thou couldst wish, with all thy heart, that a dispensation might be procured for thee to break now and then a command without forfeiting thy claim to the promise; but, because that is not to be hopes for, thou art so kind to thyself, as to give thyself leave to bow down to some idol of pleasure or profit that thou hast set up in thy heart, and hopest God will be merciful to thee, because it is only in this or that one way thou makest bold with him in. If this shoe fit thy foot—this be the true character of thy heart—which God forbid! thou hast no one lot belongs to thee in the lap of the promise. We have a comfortable promise, Ps. 50:15 but a guard is set about it, that no disobedient wretch should gather its sweet fruit: ‘But unto the wicked God saith, What hast thou to do,...that thou shouldest take my covenant in thy mouth, seeing thou hatest instruction, and castest my words behind thee,’ ver. 16, 17. On the other hand, if thou canst in truth say that it is not the holy command thou art offended with, but with thyself, because thou canst obey it no more perfectly—that it is not grievous to thee to keep, but break the laws of God; and, though thy foot too often slips, yet thy heart cleaves to them, and will not let thee lie where thou fallest, but up thou gettest to mend thy pace, and mind thy steps better—for thy comfort know, poor soul, this sincere respect thou hast to the commandment is a most comfortable evidence for thy true title to the promise. When David was able to vouch his love to the command he did not question his title to the promise; Ps. 119:113, there he asserts his sincere affection to the precepts: ‘I hate vain thoughts: but thy law do I love.’ Mark, he doth not say he is free from vain thoughts, but he hates them. He likes their company no better than one would a pack of thieves that break into his house. Neither saith he that he fully kept the law; but he loved the law, even when he failed exact obedience to it. Now from this testimony his conscience brought in for his love to the law, his faith acts clearly and strongly on the promise in the next words, ‘thou art my hiding place and my shield: I hope in thy word,’ Ps. 119:114.
Answer Fourth. If thou questionest thy right to one promise, inquire whether thou canst not discern thy interest in a second, which, if thou canst, thou mayest conclude thou hast a right to that other thou didst doubt of, yea and to all the rest. For, as there is a concatenation of graces—he that finds one hath all —so of promises, he that is heir to one hath right to all. May be, when thou readest that promise, ‘Bles¬sed are the pure in heart: for they shall see God,’ Matt. 5:8, the remainders of corruption, not yet fully morti¬fied in thy heart, scare thee from applying it to thyself as thy portion. But, for its next neighbour promise, ‘Blessed are they which do hunger and thirst after righteousness: for they shall be filled,’ ver. 6, haply thou feelest such a pinching sense of thy guilt, and want of holiness, as will enforce the to acknowledge, that if ever man in a burning fever thirsted for drink, or one half starved desired food, then dost thou crave and cry for the righteousness of Christ to justify thy person, and grace from Christ to sanctify thy nature, —so that thou canst not but see this promise spoken to thee. And if this belongs to thee, then the former, and all the other with it. For they are branches in the same covenant, which God doth not dismember, but gives it entire with all the branches growing on it to be the believer’s portion. Hence it is they are called ‘heirs of promise,’ Heb. 6:17. Not heirs of this promise or that, but ‘of promise’—that is, of the covenant, which comprehends all the promises of the gospel. So that, as he hath hold of the man’s whole body that hath fast hold of his hand—though it be but one member of it—because it is knit to the rest, and by it he may draw the rest to him; so, if thou hast hold of any one promise thou hast hold of all other, and may¬est infer thy right from this to them. And as one may draw out the wine of a whole hogshead at one tap, so may a poor soul derive the comfort of the whole covenant to himself through one promise which he is able to own and apply. ‘We know,’ saith Saint John, ‘that we have passed from death unto life, because we love the brethren,’ I John 3:14. Eternal life is the cream and top of all covenant blessings. Now, a poor Christian may, upon the inward feeling of this one grace of love in his heart—being the condition annexed to this promise—know that he is in a state of life and happiness. And why? Because wherever this grace is in truth there are all other saving graces. Christ is not divided in these, and consequently he that can apply this promise hath a right to all.
