If the Holy Spirit doesn't know everything, how can he be God?

The assertion that the Holy Spirit lacks knowledge is based on a misreading of Jesus' statements regarding the knowledge of the day and hour of his coming. In Matthew 24:36 and Mark 13:32, Jesus emphasizes that no one knows this information, not even the angels or himself, but only the Father. This does not imply a lack of divinity or knowledge in the Holy Spirit; rather, it highlights the specific context of Jesus' discussion. The phrase 'no one knows' is not universally inclusive but can refer to a limited group, as demonstrated by other scriptural examples where similar phrases are used. For instance, in Revelation 19:12, it is stated that 'no one knows' a certain name except for Jesus himself, which does not imply that the Father lacks knowledge. Instead, it indicates that only certain beings have access to that knowledge. Thus, the claim that the Holy Spirit's lack of knowledge disqualifies him from being God is unfounded and misinterprets the nature of divine knowledge as presented in Scripture.
