The reason I asked is because I can show verses that show that salvation is of grace and not of works.
It's not that I don't believe salvation to be attended by supernatural and natural works. I definitely do. Salvation itself is supernatural. But I for one have never spoken in anything other than learned human language. I have been baptized by the Spirit into Christ and baptized by Christ with the Spirit...which, incidentally, are separate spiritual experiences. One is performed by Christ and the other by the Spirit.
Fruit is how one measures the reality of a changed heart.
I agree that receiving the Holy Spirit does not automatically occur when a person is baptized in water in the name of Jesus. This idea is not consistent with scripture.
Consider, however, at what point, and what evidence confirms the arrival of the Holy Spirit into one's body. The accounts I shared reveal both points. (Acts 2:4, 38-42, 8:12-18, 9:17-18, 10:43-48, 19:1-7, 22:16)
Consider Acts 2:4, the Holy Spirit was received by those who had, prior to the event, accepted that Jesus was the resurrected Son of God.
Consider those in Acts 8. The people knew that had not received the Holy Spirit. How did they know this?
Consider Jesus' words in Luke 11:13. God gives the Holy Spirit to those who ask. How does one know they need
to ask?
Consider Paul's question in Acts 19:2. And what the entire account reveals about when the Holy Spirit is actually
received, and the evidence that proved the experience took place. (Acts 3:7)
Lastly, consider that Paul understood there is no difference in the Spirit of God and the Spirit of Christ, they are one in the same:
"But ye are not in the flesh, but in the Spirit,
if so be that the Spirit of God
dwell in you. Now if any man have not the Spirit of Christ, he is none of his." Romans 8:9
