"I TAKE him as my PRIEST, to be saved by his death and merits alone; and renouncing my own righteousness as filthy rags, I am content to be clothed with his righteousness alone; and live entirely upon free grace; likewise I TAKE him for my ADVOCATE and INTERCESSOR with the Father: and finally, I TAKE him as my KING, to reign in me, and to rule over me, renouncing all other lords, whether sin or self, and in particular my predominant idol; and in the strength of the Lord, do resolve and hereby engage, to cleave to Christ as my Sovereign Lord and King, in death and in life, in prosperity and in adversity, even for ever, and to strive and wrestle in his strength against all known sin; protesting, that whatever sin may be lying hid in my heart out of my view, I disown it, and abhor it, and shall in the Lord’s strength, endeavor the mortification of it, when the Lord shall be pleased to let me see it. And this solemn covenant I make as in the presence of the ever-living, heart-searching God, and subscribe it with my hand, in my chamber, at Dunse, about one o’clock in the afternoon, the fourteenth day of August, one thousand six hundred and ninety-nine years."
