Certain sects of poor Bible students wrongly imagine that God must first give the Holy Spirit to sinners before they can hear and understand God. That is not what the Bible teaches.The Holy Spirit or Holy Ghost is God, part of the Blessed Trinity or Godhead of God, the One God. Heres a quote denoting the personality of the Holy Spirit functioning as God from the Book of Acts 13:1-5
Peter told a crowd of sinners that if they would repent and believe the gospel then they would receive the gift of the Holy Ghost.
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
God also told us that sinners who reject what God has clearly revealed unto them will be condemned without excuse, clearly showing that unsaved sinners can hear and understand God.
