But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God. And Ananias hearing these words fell down, and gave up the ghost: and great fear came on all them that heard these things. Acts 5:3-5

One of the clear scriptures that the Holy Spirit is God is Acts Chapter 5. Here we see a married couple , Ananias and Sapphira , sold a piece of property to give the profits to the Church, which sounds like a good thing. However they lied to the Holy Spirit about how much they made, and hid some of the money for themselves

Peter called them out on their sin, and when Ananias confessed his sin , immediately died. This event obviously brought great fear among the Church. I believe God used this moment to demonstrate that the Holy Spirit is God and as Jesus taught “Blasphemy against the Holy Spirit is an unforgivable sin” (Matthew 12:31)

As Peter stated “You have not lied to men but to God” , its very clear that the Holy Spirit is God and we should pay honor and respect to the Holy Spirit as we do the Father and Son. 

And the young men arose, wound him up, and carried him out, and buried him. And it was about the space of three hours after, when his wife, not knowing what was done, came in. And Peter answered unto her, Tell me whether ye sold the land for so much? And she said, Yea, for so much. Then Peter said unto her, How is it that ye have agreed together to tempt the Spirit of the Lord? behold, the feet of them which have buried thy husband are at the door, and shall carry thee out. Acts 5:6-9

Then his wife Sapphira tried to lie to the Holy Spirit also and was immediately struck down with death. As Peter said “How can you tempt the Spirit of The Lord”? Again it demonstrates the deity of The Holy Spirit. Again this sent a strong message to the Church, the fear of God was among all of them!

Then fell she down straightway at his feet, and yielded up the ghost: and the young men came in, and found her dead, and, carrying her forth, buried her by her husband. And great fear came upon all the church, and upon as many as heard these things. Acts 5:10-11

As it stated “A great fear came upon all the Church” Do you think God was trying to send a message? The message is The Holy Spirit is God and Blasphemy against the Holy Spirit will not be forgiven or tolerated. How many false prophets and religions should read this chapter! Scripture is clear The Father , Son, and Holy Spirit is God Amen!
