When Jesus introduced the Holy Spirit to the disciples, He called Him another Helper (John 14:16). The Greek word Jesus used for another is allos, which means another of the same kind, in contrast with heteros, another of different kind or quality. The same likeness of nature that bonds the Father and the Son is revealed in the relationship between the Son and the Holy Spirit.
The divinity of the Holy Spirit is also attested by His role in the inspiration of the Scriptures, a function that Jesus explicitly acknowledged. He argued that David himself said by the Holy Spirit (Mark 12:36, NKJV) what is recorded in Psalm 110:1.
While on this earth, Jesus was constantly under the direction of the Holy Spirit. After being anointed by the Spirit in His baptism (Matt. 3:16-17), He was led by the Spirit into the wilderness (Luke 4:1, NKJV). Victorious over the tempter, He returned in the power of the Spirit to Galilee to carry on His ministry (Luke 4:14, NKJV). The miracles He performed were done through the Holy Spirit (Matt. 12:28). The fact that the Son of God depended on the Spirit is another demonstration of the divine character of the Spirit, for it’s hard to imagine the Son of God dependent upon anything less than the Divine.
Further evidence for the deity of the Spirit lies in His association with the Father and the Son in texts that mention the three Persons as equal. Thus, Jesus commissioned the apostles to baptize the new disciples in the name of the Father and of the Son and of the Holy Spirit (Matt. 28:19, NKJV).
How do the following verses help us to understand the divinity of the Holy Spirit? See Matt. 12:31-32.
The comparison between speaking against the Son of Man, a sin that may be forgiven, and speaking against the Holy Spirit, a sin that cannot be forgiven, shows that the Spirit is not a common being. Blasphemy is a sin committed directly against God. Thus, we conclude that the Holy Spirit is one of the three Persons of the Godhead. Though much has been written about the unforgivable sin, the immediate context shows people so hardened against the Spirit and His role in salvation that they attribute His work to the devil!
