C.H. Spurgeon addresses the troubling state of the church in February 1890, expressing his unwavering confidence in the ultimate victory of God's truth despite the rise of modern thought and error within the visible church. He warns against the complacency of good men who fail to recognize the dangers posed by false teachings, emphasizing the need for vigilance and protest against such trends. Spurgeon shares a letter from a concerned brother highlighting the decline in doctrinal integrity in some congregations, where heretical views are being accepted. He calls for a return to the old truths and cautions that neglecting these issues could lead to significant harm. Spurgeon's earnest plea is for the church to heed these warnings and remain steadfast in their faith.
