The Greek word translated “Comforter” or “Counselor” (as found in John 14:16) is parakletos. This word means “one called to the side of another”. Jesus is speaking about the Holy Spirit, who travels beside the Christian to guide, comfort, and to counsel. Ultimately speaking God’s spirit is our true Counselor. What we learn from the Holy Spirit also helps us help others too.
In the field of Christian Counseling, the good minister or believer has the spirit upon him (Isaiah 61~) and can go forth to further comfort, counsel, or to assist others. A Christian counselor can be fully equipped due to his or her textbook, the Holy Bible. It is completely adequate… “All Scripture is God-breathed and is valuable for teaching the truth, convicting of sin, correcting faults and training in right living; thus anyone who belongs to God may be fully equipped for every good work.”–2 Timothy 3:17. Admittedly this is a presuppositional view but unless there exists a chemical imbalance or drug abuse, which may require medical help, Christian counseling motivated by the Spirit and Scriptures is fully adequate to do the job!
