Hebrews 6:4-6 says; For it is impossible to bring back to repentance those who were once enlightened—those who have experienced the good things of heaven and shared in the Holy Spirit, who have tasted the goodness of the word of God and the power of the age to come— and who then turn away from God. It is impossible to bring such people back to repentance; by rejecting the Son of God, they themselves are nailing him to the cross once again and holding him up to public shame. The writer of Hebrews is warning those in the faith not to allow unconfessed sin to pile up in such a way that they totally drift from God and reject the gospel or grieve the Holy Spirit. This is a deliberate and final decision that cannot be undone. Jesus says in Matthew 12:37; Every sin or blasphemy can be forgiven– except blasphemy against the Holy Spirit, which can never be forgiven. The apostle Paul almost repeats Jesus’s words in Ephesians 4:30 by saying; And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. We have assurance in Jesus Christ. We have been saved by grace and we open the gift of salvation by faith. Paul says in Romans 5:1; Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ. We have peace with God in Christ. Paul says in Romans 8:38-39; For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord. God will never stop loving anybody, even those who have rejected Him. Secondly nothing or no one on this earth can separate us from God’s salvation in Christ except us. We are free to choose just like Adam and Eve were free to choose in the garden of Eden. There will be no one in heaven who does not want to be there. Praise God that He has redeemed us by the blood of Jesus Christ where we have peace and assurance and the freedom to choose.
