God has sent the Holy Spirit to save men from sin and its consequences. From the introduction "in the work of uniting the individual soul with God's purpose that 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."
