Joseph Irons (1785-1852) was one of the ablest preachers of his day, and a powerful and prolific writer. His doctrinal teaching was pellucidly clear and consistent; he was a profound student and sound expositor of the Word of God, and many were influenced by his sermons, spoken and printed, and confirmed in the faith of God's elect. He was a determined foe of Romanism and Ritualism, deeply interested in the welfare of the young, and ready to aid any effort that commended itself to him on the basis of the faith for which he so earnestly contended. Many of his hymns have secured a permanent place in our hymnology, and his sermons are doctrinal, experimental, and practical in the best sense of the words. He never ceased to preach Christ, making Him the Alpha and Omega of all his discourses. He was born at Ware, in Hertfordshire, and brought up under the care and counsel of a godly father, who was a builder, and who trained his son in that trade. When he left his father's roof, he tells us the parting words were, "There's poor Joseph going to that wicked London. My heart bleeds while I bid him good-bye. I fear it will end in his ruin. You will be far away from a father's eye and a father's counsel, but never will I cease to pray for you that God may preserve and prosper you, although surrounded with so much that is evil." The youth was but eighteen when, in 1803, God led him to the Church of St. Mary Somerset, Thames Street, to hear W. Alphonsus Gunn, and there the arrow was directed into his conscience and he was brought to a saving knowledge of Divine truth. In 1808 his first sermon was preached over a smith's shop at Dulwich; he was actively engaged in business, but on most Sundays would walk from ten to twenty miles, preaching in various villages. "My only companions were my pocket Bible and its Divine Author, who often favored me with the spirit of prayer on the way and shed many a ray of Divine light on the inspired page, so that I was furnished with a 'Thus saith the Lord.'"
After six years' service in Hertfordshire, he became pastor of the Church at Sawston, near Cambridge, and in January, 1818, he preached his first sermon in Camberwell. Ultimately, Grove Chapel was erected and opened on July 20th, 1819, and within its walls until the time of his death he continued proclaiming the Gospel; his mortal remains rest in a vault under the pulpit. In his last sermon, about ten days before his decease, he spoke of heaven in joyful terms; "I confess that my soul longs for it, and I anticipate meeting with prophets and apostles and patriarchs, and above all, with Jesus Himself, to behold Him face to face in glory, to be like Him, and to see Him as He is."
His published writings were numerous, some running into many editions. "Jazer," letters on Gospel doctrine; "Nathaniel," letters on Christian experience; "Nymphas," an exposition of the Song of Solomon; 611 original hymns; and a paraphrase of the Book of Psalms, are among the number. He established a Home Mission and other Societies for visiting and assisting the sick poor, and to the end of his life he was one of the best friends and helpers of the Aged Pilgrims' Friend Society. This great man was no idler in the Lord's vineyard. He talked not about "working for Christ," but delighted to magnify his glorious Lord. His sermons should be models for our preachers today in their perspicuity, plainness and power. He could not cut and trim to the times. His faithfulness gave offense to many whose creed and conduct could not bear the blaze of truth and the pointed appeals he made to conscience. Many hard speeches were made against him, but he remained unmoved as an iron pillar. As a man he had very tender, feeling and often smarted under the unkind treatment of those of whom better things might have been hoped; but neither the fawning of one party nor the frowns of the other could shake his firmness. When at home in his "Shepherd's Tent, "Grove Lane, he used very frequently to visit his chapel; to him it was a peaceful, private promenade, after the close confinement of his study, in which he spent many hours every day. Covenant love, covenant blood and covenant grace were his constant theme. His dying desire, so graciously fulfilled, was that Grove Chapel "might never be desecrated with another gospel." Someone told him that he put too much in his sermons and should reserve ideas for future use. He replied, "Thank God I obtain my materials from heaven; my Master knows what things I have need of, and having called me, He will not allow me to work alone. I get my sermons on my knees with the Word of God before my eyes and if I empty my seed-basket today, I know He will fill it tomorrow; therefore I will, God helping me, tell it all out, or it would be like a fire in my bones, burning its way out." Grove Chapel recalls many memories of those who have gone before; in its schoolroom is a unique collection of portraits of free grace ministers of various sections of the one Church. In #5 pew in the Chapel is the spot where the Lord first met with the "Wayside Notes" writer, broke him down in contrition of heart and revealed Christ to him as all his salvation, and there are friends still with us who can testify to the power of Mr. Irons' ministry, when in their early years they sat under it.
