On Pentecost, Jesus Christ sent the Holy Spirit to the apostles, marking a significant moment for the early church as it grew by thousands. In the account of Ananias and Sapphira, Peter confronts their deception by asking why satan filled their heart to lie to the Holy Spirit, indicating that through His Spirit, God knew not only their actions but also their hearts. Their sin led to their immediate death, serving as a sobering lesson to the church about the seriousness of living by God's word. Regarding the nature of the Holy Spirit, it is never described in the Bible as having a humanlike shape, unlike the Father and the Son. The only form attributed to the Spirit is that of a dove during Christ's baptism, though some suggest it descended in a visible form like a dove rather than being shaped as one. This distinction highlights that the Spirit does not share the human image in which man was created, setting it apart from the Father and the Son.

The Holy Spirit, often described in imagery such as a dove, is presented as the power of God, not a distinct personality within the God family. At Jesus' baptism in John 1, the Spirit is depicted as descending like a dove, symbolizing peace and gentleness, yet it is emphasized that the Holy Spirit is not a bird or a literal creature. Theologians may dismiss the literal interpretation by calling it a mystery, but they acknowledge it as the power of God manifesting in a harmless and gentle form. Jesus Himself, in John 3:8, describes the Spirit as invisible, like the wind, where its effects are observable, but its source and destination remain unseen. Further, in John 7:37, Jesus uses water as a metaphor for the Spirit, illustrating it as flowing from within, which challenges the notion of it being a personality. The Holy Spirit is consistently portrayed as an inanimate force, emanating from the Father and the Son, enabling communion with God and aiding in the spiritual creation of His kind. It dwells within believers, not as a person, but as the divine power that transforms and connects them to the Father and the Son, reinforcing its role as the means through which God's will is accomplished.
