Who is the Holy Spirit?

The Holy Spirit is the third Person of the Trinity—fully God, co-equal with the Father and the Son, and deeply personal. He is not a force or influence but a divine Person who speaks, teaches, comforts, and guides. As God, the Holy Spirit possesses all divine attributes: He is eternal (Hebrews 9:14), omniscient (1 Corinthians 2:10–11), omnipresent (Psalm 139:7–10), and holy (Romans 1:4). He was active in creation (Genesis 1:2), inspired the Scriptures (2 Peter 1:21), and continues His work today by indwelling and empowering believers.

The Holy Spirit is also called the Spirit of Christ, the Spirit of Truth, the Comforter, and the Counselor. He is the One who applies the finished work of Jesus Christ to the lives of those who believe, working in them to transform, equip, and sustain them in their walk with God.

Receiving the Holy Spirit

A person receives the Holy Spirit at the moment of genuine salvation—when they repent of their sins, put their faith in Jesus Christ as Lord and Savior, and are born again. This is not based on emotion or religious effort, but on God’s promise.

When someone turns to Christ in sincere faith—trusting in His death and resurrection for the forgiveness of sins and surrendering to His Lordship—the Holy Spirit comes to dwell within them permanently. This marks the beginning of a new spiritual life and relationship with God.

Acts 2:38 – “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”

Ephesians 1:13 – “When you heard the word of truth, the gospel of your salvation, and believed in Him, you were sealed with the promised Holy Spirit.”

Romans 8:9 – “…Anyone who does not have the Spirit of Christ does not belong to Him.”

Receiving the Holy Spirit is not a second event after salvation—it is the automatic and essential result of true faith in Christ. From that moment on, the Spirit begins His full work in the believer’s life.

The Role of the Holy Spirit in the Life of the Believer
