As long as individuals are content with a theory of truth, and are yet lacking in the daily operation of the Spirit of God upon the heart, which is manifested in outward transformation of character, they are cutting themselves off from the qualification that would fit them for greater efficiency in the Master's work. Those who are devoid of the Holy Spirit cannot be faithful watchmen upon the walls of Zion; for they are blind to the work that ought to be done, and do not give the trumpet a certain sound. 2SM 56.2
The baptism of the Holy Ghost as on the day of Pentecost will lead to a revival of true religion and to the performance of many wonderful works. Heavenly intelligences will come among us, and men will speak as they are moved upon by the Holy Spirit of God. But should the Lord work upon men as He did on and after the day of Pentecost, many who now claim to believe the truth would know so very little of the operation of the Holy Spirit that they would cry, “Beware of fanaticism.” They would say of those who were filled with the Spirit, “These men are full of new wine.” 2SM 57.1
The time is not far off now when men will want a much closer relation to Christ, a much closer union with His Holy Spirit, than ever they have had, or will have, unless they give up their will and their way, and submit to God's will and God's way. The great sin of those who profess to be Christians is that they do not open the heart to receive the Holy Spirit. When souls long after Christ, and seek to become one with Him, then those who are content with the form of godliness, exclaim “Be careful, do not go to extremes.” When the angels of heaven come among us, and work through human agents, there will be solid, substantial conversions, after the order of the conversions after the day of Pentecost. 2SM 57.2
Now brethren, be careful and do not go into or try to create human excitement. But while we should be careful not to go into human excitement, we should not be among those who will raise inquiries and cherish doubts in reference to the work of the Spirit of God; for there will be those who will question and criticize when the Spirit of God takes possession of men and women, because their own hearts are not moved, but are cold and unimpressible.—Letter 27, 1894. 2SM 57.3
