Faced with the question of who the Holy Spirit is, lots of Christians battle to find words. Many find the question confusing – is the Holy Spirit a force, person or something else? This excerpt from an article courtesy of HelloChristian sheds light on this question.
In Scripture..we see that the Spirit is not third in rank in the Godhead but is co-equal and co-eternal with the Father and Son, sharing with them all the glory and honor due unto our Triune God. The Holy Spirit is not an impersonal power or an ethereal, abstract energy. The Spirit is personal in every sense of the term. He has a mind and thinks (Isa. 11:2; Rom. 8:27). He is capable of experiencing deep affections and feelings (Rom. 8:26; 15:30). The Spirit has a will and makes choices (Acts 16:7; 1 Cor. 2:11) regarding what is best for God’s people and what will most glorify the Son.
We see even more of the Spirit’s personality when he is described as being grieved when we sin (Eph. 4:30). The Spirit, no less so than the Father and the Son, enters into a vibrant and intimate relationship with all whom he indwells (2 Cor. 13:14). The Spirit talks (Mark 13:11; Rev. 2:7), testifies (John 15:26; 16:13), encourages (Acts 9:31), strengthens (Eph. 3:16), and teaches us, especially in times of spiritual emergency (Luke 12:12). That the Spirit is personal is seen in that he can be lied to (Acts 5:3), insulted (Heb. 10:29), and even blasphemed (Matt. 12:31-32).
Above all else, though, the Holy Spirit is the “Spirit of Christ” (Rom. 8:9). His primary role in us, as the temple of God in whom he dwells (Eph. 2:21-22), is other-directed or other-oriented as he ministers to direct our attention to the person of Christ and to awaken in us heartfelt affection for and devotion to the Savior (John 14:26; 16:12-15). The Holy Spirit delights above all else in serving as a spotlight, standing behind us (although certainly dwelling within us) to focus our thoughts and meditation on the beauty of Christ and all that God is for us in and through him.
