The messages in this book were prepared for Sunday morning preaching-this is a sermonic study of the Holy Spirit. Each chapter formed the basis for a Sunday morning sermon at Parke Memorial Presbyterian Church, Evansville, Indiana. Built on sound interpretive principles and procedures from an evangelical stance, these studies were prepared for laypersons not necessarily for scholars or exegetes. The Doctrine of the Holy Spirit is of interest to all with questions about successful Christian living. The Holy Spirit is the Person and Power for spiritual success. As a believer, God does not expect you to do just the best you can in your journey of faith. God the Father and God the Son sent the Holy Spirit to be the spiritual dynamic in that journey. God told Zerubbabel, Not by might, nor by power, but by My Spirit says the Lord of hosts (Zechariah 4:6). It is the challenge of each believer, therefore, to fully embrace the Spirit of God and experience all the blessings God has for His children.
