The saints everlasting rest

1. Consider, a heart set upon heaven, will be one of the most unquestionable evidences of a true work of saving grace upon thy soul. Would you have a sign infallible, not from me, or from the mouth of any man, but from the mouth of Jesus Christ himself, which all the enemies of the use of marks can lay no exceptions against? Why here is such a one, Mast. vi. 21. Where your treasure is, there will your heart be also. Know once assuredly where your heart is, and you may easily know that your treasure is there. GOD is the saints treasure and happiness: heaven is the place where they fully enjoy him: a heart therefore set upon heaven, is no more but a heart set upon GOD, desiring this full enjoyment: and surely a heart set upon GOD through Christ, is the truest evidence of saving grace. External actions are the easiest discovered; but those of the heart are the surest evidences. When thy learning will be no good proof ⟨p. 279⟩of thy grace; when thy knowledge, thy duties, and thy gifts will fail thee, when arguments from thy tongue and thy hand may be confuted; then will this argument from the bent of thy heart prove thee sincere. Take a poor christian that can scarce speak English about religion, that hath a weak understanding, a failing memory, a stammering tongue, yet his heart is set on GOD, he hath chosen him for his portion, his thoughts are on eternity, his desires there, his dwelling there; he cries out, O that I were there! he takes that day for a time of imprisonment, wherein he hath not taken one refreshing view of eternity. I had rather die in this man's condition, than in the case of him that hath the most eminent gifts, and is most admired for parts and duty, whose heart is not taken up with GOD. The man that Christ will find out at the last day, and condemn for want of a wedding-garment, will he be that wants this frame of heart. The question will not then he, how much you have known or talked? but, how much have you loved, and where was your heart? Why then, as you would have a sure testimony of the love of GOD, and a sure proof of your title to glory, labour to get your hearts above. GOD will acknowledge you love him, when he sees your hearts are set upon him. Get but your hearts once truly in heaven, and without all question yourselves will follow. If sin and satan keep not thence your affections, they will never be able to keep away your persons.
