My personal comments: I think that sometimes we should perhaps be praying to the Holy Spirit for guidance here on earth since He was personally sent down to be with us and guide us. It appears that many of us ignore the Holy Spirit and go straight to God or Jesus. Although they are all the same person, there was a reason why Jesus, when he ascended to Heaven, sent down the Holy Spirit to be with us and for us. We should, perhaps, give more attention to the Holy Spirit than most of us do. This is open to much conversation, but we must keep in mind that God/Jesus “SENT” the Holy Spirit to be with US. We should not ignore His presence.
How can God the Father, the Son and the Holy Spirit be one. Hey, I am a grandfather, a father and also a son , but yet there is only one of me. But I act as three people on different occasions.
