This is a rather personal/family story, but am happy to be able to share it. My apologies for the length, but I trust it will be worthwhile! (Note: the sermon mentioned very well MAY have been an open-air sermon.)
Going through my parents' things, I came across and old book -- a biography of my great-great-not-sure-how-many-greats grandfather. Please hear the dear testimony of this now-long-gone man. He wrote this in 1773 [links added by me, obviously]:
"CHARLES DIXON came from Yorkshire, England, to Nova Scotia in the year 1772, and settled at Sackville, N. B. (New Brunswick).
I, Charles Dixon, was born March 8, old style, in the year 1730, at Kirleavington, near Yarm, in the East Riding of Yorkshire in Old England. I was brought up to the Bricklayer's trade with my Father... At the age of thirty-one I married Susanna Coates, by whom I have had one son and four daughters.
I was brought up a Protestant, or a member of the Church of England, and endeavored to demean myself as one on his Christian race; to live soberly, righteously and Godly in this present evil world, thinking, or at least had no doubt but I should obtain heaven at last.
But being at one time at Robinhood's Bay, near Whitby, I went to hear Thomas Secomb, a Methodist preacher, so called by way of derision. But his preaching was such as I never before heard, for his word was with power, it made me cry out in the bitterness of my soul, what must I do to be saved?
All my pretence of being a member of the church fell to the ground, I was condemned by her articles and homilies. I had broken my baptismal covenant, and was in fact a baptized heathen with a Christian name. For the space of about twelve months I went mourning all my days under a sense of guilt, and bowed down with the Spirit of bondage, but seeking for and asking of God, that Spirit wherewith He made His children free; that I might rejoice with his chosen, and give thanks with his inheritance. At length on Wednesday, September the 21st, 1757, while seeking and striving upon my knees, the Lord proclaimed his name merciful and gracious to forgive my iniquities, healed all my diseases, and set my soul at liberty. ..."
Note that for a number of generations, in the late 1700s and 1800s, a number of my subsequent male ancestors were Methodist preachers -- back when Methodism was still truly Christian and gospel-centered. I look forward to meeting many of them some day! Praise be to Christ!
By the way, he and his wife Susanna (which is also my wife's name) ended up with 8 children, though they had only 5 when he wrote this. The Lord has blessed me and my Susanna with 7.
Also, I was saved by the same gospel preaching of a Wesleyan(Methodist) preacher -- such preaching I had never before heard! -- back when I was in college. The Lord showed me my lost estate, that I was a sinner in need of salvation, and forgiveness was by faith in Christ, not by works. I'm not an Arminian, but I do love and appreciate my gospel-preaching Bible-believing Arminian brethren!
