In Vickers [the author's] opinion, Paine's God differs from the widely spread notion of God during the period of Enlightenment. As she puts it: "Paine's deist God connected with the need for humanitarian philanthropy should not be confused with a theistic God who is completely transcendent, utterly unknowable, and completely independent of His creation. So the principal difficulty with the theistic deity is that there is no incentive to pray or worship God. In contrast, Paine's deist God was knowable, at least to the point of establishing God's benevolent nature. More importantly, Paine's God both watches and judges mankind and has an active role in His creation. Humanitarianism in Paine's system, therefore, was not only logical, but necessary." (p. 123) "He envisioned nations (in particular Great Britain) that took responsibility for the welfare of its citizens." (p. 8)
Incidentally, the source for the phrase, my pen and my soul have ever gone together, comes from The American Crisis, Number II , October 11, 1779 (page 72), where Paine explains:
What I write is pure nature, and my pen and my soul ever go together. My writings I have always given away, reserving only the expense of printing and paper, and sometimes not even that. I never courted either fame or interest, and my manner of life, to those who know it, will justify what I say.
