And I don't doubt the Holy Spirit's existance here with us at all times because Jesus told us (John 14:16) And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; [Even] the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
Also: (John 14:26 -- John 15:26 -- John 16:7 )
Those that recognize the spirit of truth have the Holy Spirit within them.... To be baptized is an act of righteousness, and obedience. And those righteous acts are known as our works that will follow us (Revelation 14:13) And I heard a voice from heaven saying unto me, Write, Blessed [are] the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
And To be baptized is to be bury with Christ ( Romans 6:4) Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Do you hear what Jesus said in?---> Luke 12:8 Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God: But he that denieth me before men shall be denied before the angels of God. Luke 12:10 And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.
