yes, the Holy Spirit is real, and Yes you can feel it... It's God in You! That's the bottom line, imagine that, God In You! It's His spirit in you..... The Holy Spirit can do great things...Apostles performed miracles via the Holy Spirit, after all.. we cant do miracles by ourselves. It enabled the early Church to speak in tongues, as some people today still possess that gift.
The Holy Spirit is God's Spirit....
