Friend, if you are not sure of Heaven or Eternal Life, I urge you right now, just as you are: a condemned sinner destined for eternal punishment, simply trust Jesus Christ for who He is – God, who came to earth, died on the cross for you – to pay for ALL your sins. He arose from the grave proving He is God and pleads with you to receive (trust) Jesus Christ as your Savior. He paid the price for your eternity to be with Him in Heaven.
The following is a summary of God’s Plan of Salvation:
All men are sinners: Romans 3:10; Romans 3:23; Isaiah 64:6; James 2:10
The penalty of sin is death: Romans 6:23; Ezekiel 18:20
You must be perfect to enter Heaven: Revelation 21:27
Man can do nothing of himself to obtain this perfection: Ephesians 2:8-9; Galatians 2:16; Romans 4:5
God provided a sin-bearer, Jesus Christ (God in the flesh, who died and rose from the dead) and gives to man His righteousness: II Corinthians 5:21; Philippians 3:9; Isaiah 53:6; I Peter 3:18
People need only to repent of their sins and believe/trust in the Lord Jesus Christ as personal Savior for salvation. John 3:16; John 1:12; Acts 16:31
You can be absolutely certain of your salvation ow, and that this salvation cannot be lost because eternal life is a guarantee from God: John 6: 37-39; John 10:28; I Peter 1:5; Hebrews 10:10-14; I John 5:13
