Classic Christian author A. J. Gordon expresses curiosity about whether the healing miracles from the Middle Ages up to his day can be verified as a continuation of Christ's Spirit in the church. Through deep study and inquiry of the established history, Gordon concludes that the power to heal followers remains with the church—there was no special era of miracle working. God and His powers remain the same in the modern era as they have right through human history. For Gordon, God's intervention in the suffering and sickness of His followers is frequent; the will of the Lord however is variable—but He will not prolong the pain of someone whose illness is too great. Throughout this text, A. J. Gordon makes his argument from a biblical perspective, citing passages in both the Old and New Testament that support the continuation of spiritual gifts. Quoting testimonies of believers across the ages, he offers a convincing argument that the church ministry is, to this day, one of healing.
