Dec 18th 2012: Baptism with the Holy Spirit.
A B Simpson clearly taught the necessity of a baptism of the Holy Spirit subsequent to conversion. Tozer wrote "When a man is filled with the Holy Spirit, he knows it!" - a definite experience. I believe it was also Tozer who wrote, concerning "Dispensationalism" - the belief that the church received its baptism in the Holy Ghost at Pentecost and we require nothing more now than we received at conversion. He wrote, "Dispensationalism is more dangerous than liberalism - liberalism has cost us our message, dispensationalism has cost us our power!"
In 1905 Simpson wrote a long article for the Alliance magazine, Living Truths, on the subject of The Baptism of the Holy Spirit, A Crisis or an Evolution. He concluded: "The truth I have been endeavoring to demonstrate is intensely practical. So long as people think they have it all, there is little incentive to rouse themselves and claim their full inheritance, but when God's people see that like Israel of old, they are still toiling in the wilderness under His displeasure, that they are neglecting a great salvation, that they are out of fellowship with Christ and grieving the Holy Ghost, motive is supplied of overwhelming power and they are led to a heart searching, humiliation and unceasing prayer, and a new impulse comes into their lives like a great tidal wave over the ocean of love, and an experience comes to the soul as much higher than conversion as conversion was better than the old life of flesh and sin. This is the deepest need of the church today. One such consecrated, Spirit-filled life means a score of souls for God. 'Let us therefore fear lest the promise being left us of entering into His rest any of you should seem to come short of it.'"
