No one can really explain the Trinity of God. 1 God and yet 3 persons? But that’s what it is. Do we have to understand it at the moment? No; maybe one day in heaven. But for now, we just accept the divine Trinity by faith.
Jesus? Also OK.
But the Holy Spirit? Many newborn Christians (still) have their problems with it. No problem, because we are all still learning and progressing on our spiritual journey.
Does every newborn Christian have the Holy Spirit?
Every newborn Christian is given the Holy Spirit as a Helper the moment you accept Jesus as your Savior. “When the Spirit of truth comes, he will guide you into all truth. He will not speak on his own but will tell you what he has heard. He will tell you about the future.” (John 16:13; NLT)
The Holy Spirit is omniscient. Do you foresee how powerfully God will equip you? You can go to the Holy Spirit with everything and ask for help, guidance, wisdom and knowledge. The Holy Spirit is happy to help.
You can also tell the Holy Ghost to help you understand everything correctly when reading the Bible.
