Read what I wrote. The nano second you are Born Again from above, God begins a work in you to change you into the image of Christ. You must be born again from above. No Holy Spirit = no Heaven. Now let me explain what 1 Thess. 5:19 means, because the Apostle Paul explains it in
Ephesians 4:29-31 -29 Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. 30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. 31 Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice.
You must receive the Holy Spirit to be sealed for the day of redemption.
