I Do most readily acknowledge my self a Debtor to you all, and a Servant of all, and therefore I have sent these few Lines to salute you all. My Lines did fall in a fair place when the Lord did cast my lot among you; for which I desire to be thankful. God hath been pleased to work a mutual affection between me and you. I remember the tears and Prayers that you have sent me hither with, and how I saw your hearts in your eyes; How can I forget how you poured out your Souls upon me. And truly you are a People much upon my heart, whose welfare is the matter of my continual prayers, care, and study. And oh! that I knew how to do you good: Ah? how certainly should never a son of ⟨p. 16⟩you miscarry if I knew how to save you. Ah! how it pities me to think how that so many of you should remain in your sins after so many and so long endeavours to convert and bring them in. Once more, Oh? my beloved, once more hear the call of the most high God unto you. The Prison Preaches to you, the same Doctrine that the Pulpit did Hear, O People, hear; he that hath an ear let him hear. The Lord of Life and of Glory offers you all Mercy, and Peace, and Blessedness: Oh, why should you die! whosoever will, let him take of the Waters of Life freely; what miss of life when it is to be had for the taking? God forbid. O my Brethren, my soul yearns for you, and my bowels towards you. Ah! that I did but know what Arguments to use with you: who shall choose my words for me that I may prevail with sinners not to reject their own Mercy: how shall I get within them? How shall I reach them? Oh! that I did but know the words that would pierce them? that I could but get between their sins and them. Beloved Brethren, the Lord Jesus hath made me, most unworthy, his Spokesman, to bespeak your hearts for him: And oh, that I knew but how to woo for him, that I might prevail! these eight years have I been calling, and yet how great a part do remain visibly in their sins, and how few, alas! how few souls have I gained to Christ by sound conversion. Once more I desire with all possible earnestness to apply my self to you, I have thought it may be a Sermon out of a Prison might do that which I could not do after my long striving with you, but have left undone: come then, O Friends, and let us reason together.
