The Holy Spirit is probably the most misunderstood person of the Godhead yet He is an important part of our salvation. It is a serious thing to offend Him. It robs us of peace and of usefulness. And if one continues to grieve and insult and quench Him, it may rob that person of his eternal reward.
In Matthew 8 and 9 we see some demonstrations of the power of Jesus. Some miracles were performed to help others and others to prove He was the Messiah. In every instance Jesus was in perfect control of the situation.
Who is the Holy Spirit? Many regard Him as merely an impersonal force—a sort of divine influence emanating from God. In truth He is a distinct person in the God-head, with a special work and personality.
Belief in the Trinity is one of the distinctive characteristics of the historic Christian faith. In the nature of the one God, there are three distinct Persons—the Father, Son, and Holy Spirit—each fully God, co-equal and co-eternal.
