God requires to be represented by a fiery Church. He can and does tolerate many things in the way of infirmity and error in His children. He can and will pardon sin when the penitent prays, but two things are intolerable to Him–insincerity and lukewarmness. Lack of heart, and lack of heat are two things that He loathes, and to the Laodiceans He said, in terms of unmistakable severity and condemnation: “I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of My mouth” (Revelation 3:15-16). Nothing short of being red hot for God can keep the glow of heaven in our hearts these chilly days.
