Blessed forever be the Father of light, who has called you out of the world, and has given you a testimony to finish in behalf of Christ Jesus; that through you He may manifestly declare Him to the world, in the true Savior of God, wherein you are the first-fruits of His glory, as you die and arise in Him: And so the Son is the light of the world. I beseech you, let your shining be in the right nature, and your rising be as you are born of God, and covered with the same Spirit and life by which you have been begotten towards Him: That none of you may be found false witnesses of His coming, when you are proved with fire, when nothing will abide with you but what you are in His nature: That's all you have of the treasure of God, even what you are in Him, who works in you against the flesh and the world; as many as abide in the feeling of His measure, and therein receive Him as Head over all. But if you receive anything above Him, in your minds, which is not of this nature, then you oppress Him who is meek and tender, which hinders His arising to walk and dwell in you.
Wherefore dear Friends, watch against all fleshly, selfish, hasty motions; take heed what you receive into His temple, lest you defile it, and He leave you desolate and in darkness.
Because of evil thoughts, covetousness, and pride of heart, is His Spirit grieved; every self-end, in whatever you do and suffer, is an enemy to His life, He suffers by whatever is done deceitfully towards God or man; and if you give way to wrath you deny His kingdom; yea, you that have tasted of Him, you know in measure how pure His way is in all things; and I pray you may all grow therein, being so much the more diligent, as you see your adversary seeking by all means to darken that glory of your holiness in Christ Jesus, that Spirit; to whom I commit you all, that in the holy bowels of His tender love you may know one another, in whatsoever any of you shall meet with from the world, in this way of your pilgrimage; that your unity in Him nothing may be able to break.
