No emotion to it.
The spirit of God lives inside each believer, and when He enters the change is palpable. One knows when they have received the Spirit and it has nothing to do with emotion. One is changed dramatically and one knows it immediately.
That is the best way I can describe it.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
The Holy Spirit is not going to be making up new doctrine. The Holy Spirit is the WORD not man made imaginations.
Unless you grow up believing, from the earliest age you can remember. Never having had any doubts about the diety of Christ, your sinful nature, and your need for His sacrifice as payment for your sins, leaves you without a palpable conversion experience from non-believer to believer.
You would think such a case of naturally coming to Jesus would be the ideal, yet the lack of a dramatic "transformation" can have its drawbacks, regarding assurance of being "born again". I speak from experience.
