I do not know what became of his wayward children, whether they ended up like Hophni and Phinehas or returned like prodigals to the Lord. Edward had a younger brother, William, who funeral sermon was preached by Philip Henry in 1695. William's son (Edward's nephew), Samuel Lawrence (1661-1712), was, like his father and uncle, a godly man. Matthew Henry preached his funeral sermon in 1712 and gave an account of his life, quoting also very movingly from Philip Henry's funeral sermon for his father. When it came to describing Edward, Matthew had this to say:
...his father's elder brother was Mr Edward Lawrence, an eminent minister in Shropshire first, and afterwards in London. A man of great integrity, and a substantial judicious preacher; who, to keep the peace of his conscience, left a good living, and threw himself and his numerous family upon divine Providence.
His book called 'Christ's Power over Bodily Diseases,' has been and will be of great use to many for their comfort in sickness, and their improvement of it. This nephew of his in many things resembled him much, and the comfort he had in him was the more valued by him, because of the great grief he had in some of his own children, which he let the world know something of in a book he published, called, 'Parents' Groans over Wicked Children.' He died in November, 1695.
Whether or not his erring children returned to the Lord, Edward Lawrence speaks a word even today to both parents and children that is a blessing to many, a comfort and encouragement to some, and a serious warning and reproof to others. His counsel is born of experience, and comes from loving the Lord above family relations, and thus speaking the truth to them in love, counting their souls as so very precious as to speak the truth and hide it not.
