Everyone has earned their place in hell, myself included (Romans 3:23, 6:23; Revelation 21:8). The only way that God has provided for us to get out of what we deserve is by trusting in the person and work of Jesus Christ (Romans 10:9-10; John 6:29).
Everyone who denies Jesus their entire life is in turn denied by Jesus before His Father in heaven -- Jewish, Muslim, Sikh, Hindu, Atheist, Agnostic, etc (Matthew 10:33). Since no one comes to the Father but by Christ and since He is the Only Way to the Father (John 14:6; Acts 4:12), those who deny Christ their entire lives will not be with the Father (1 Corinthians 16:22).
However, God has commanded everyone everywhere to repent (Acts 17:30), and if the man who previously denied Christ repents, changes his ways, and embraces Christ, his former sins will be forgiven (Acts 10:43; Ezekiel 18:21) and he will be able to enter into the joy of his Master (Matthew 25:23, 25:34).
I hope that you also choose to enter in through faith in Christ.
