But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. ~ John 14:26
What is the function of the Holy Spirit (Holy Ghost)? Many do not understand the doctrine of the Holy Spirit, and others still do not grasp the Person of the Holy Spirit as God within man. However, the Holy Spirit is the third Person of the Trinity, coequal with and distinct from God the Father and God the Son. The Holy Spirit is God in all His Deity with absolute sovereignty and condescension, in the complete “hiddenness and revealedness of God”. Without the work of the Holy Spirit man is not capable to decide to accept God or have the faith to be saved. According to Scripture, after salvation by Jesus Christ, the Holy Spirit is the divine authority dwelling with the believer as God in residence. Now, that is a powerful complex thought for consideration!
The Holy Spirit is the “Comforter,” which Jesus Christ referred to in John 14:26. The Holy Spirit guides nonbelievers to Jesus and enable individuals to live as Christians. The Holy Spirit gives gifts, such as wisdom, knowledge, faith, healing, miracles, prophecy, discernment, tongues, interpreting tongues, leadership, and mercy. In Acts 1:4-8, the Holy Spirit baptizes and empowers.
The Holy Spirit provides grace (Psalm 145:9; Luke 6:35), restraint from sin (2 Thessalonians 2:6-7; Romans 13:14), conviction of sin, righteousness, and judgment (John 16: 7-11), indwell the believer (1 Corinthians 6:19-20), seal the believer (Ephesians 1:13-14), lead the believer (Galatians 5:16-18), regeneration (John 1:13) as well as salvation (John 3:5). Thus, it is the Holy Spirit who produce “daily, constant communion with God the Father and God the Son”. The Holy Spirit gives God’s divine wisdom for application to everyday situations and circumstances in the life of the believer.
Wisdom that goes beyond an individual’s intellect. Wisdom that is divine in nature, and is supported by Scripture. Wisdom, which enables individuals to know God personally, interact with God, and be in constant fellowship with God. It is the Holy Spirit who enables individuals to progress and profit regardless of difficulties, because the Holy Spirit divinely interacts with and facilitates all facets of a believer’s life (1 Corinthians 12:7-11). Hence, the Holy Spirit functions in every area of the believer ‘s life, in supplication through Jesus Christ, in order to commune with God.
