"The writer, Colonel Brengle, gives us not only of the fruit of an orderly and well-stored mind on the great subject before us, but—­ and this is the more important—­he tells us of the actual work of the Holy Spirit in the lives of ordinary men and women. The Holy Spirit is our Helper. In the work of righteousness He is a Partner with us. In the life of faith and prayer He is our unwavering Prompter and Guide. In the submission of our wills to God and the chastening of our spirits He is the great Co-worker with us. In the bearing of burdens and the enduring of trial and sorrow He joins hands with us to lead us on. In the purifying of every power from the taint of sin He is our Sanctifier. All this is practical. It has to do with to-day—­with every bit of to-day. In fact, so far from the sphere of the Holy Spirit being limited to the pulpit or the platform, or to the inward experiences of the religious life, He is just as truly and properly concerned with the affairs of the shop and the street, the nursery and the kitchen, the chamber of suffering and the home of penury, as with preaching the Gospel or healing the sick."
