QUESTION: In Romans 8:16, what is the difference between the spirit which is in man and the Spirit Himself?
ANSWER: This passage teaches that the Holy Spirit (the third person of the Godhead - Matthew 28:19) bears witness with the Christian’s spirit that he or she is a child of God. This witness comes only through the Word of God! When a person accepts and is obedient to the truth given (John 16:13), his or her spirit can then witness in agreement with the Holy Spirit that he or she is a child of God; a Christian!
