“It is appointed once unto man to die, and after that the judgment,” (Heb. 9:27). There are those who believe that after they die they will go to purgatory. They believe that going into purgatory will further purify them of their sins; after this further purification of their sins, they believe they will then be acceptable to enter into heaven. This teaching is false;- it is nowhere to be found in the Bible. This teaching was introduced in 593 A.D. If this teaching is true, then what Jesus Christ accomplished on the cross for those of us who have placed our faith in all He did for us, is insufficient. The apostle Paul tells us in Galatians 1:1112 that all the revelations he received came directly from Jesus Christ, not from man. He tells us in 2nd Corinthians 5:8 concerning those of us who are Christians and die, that we go to be with the Lord - not purgatory. Paul also tells us by inspiration of the Holy Spirit in Philippians 1:19-24 that when Christians leave this life, they go to be with Christ.
We do not need any further purification if you have been born-again and are washed in the blood of Christ, Scripture tells us that our hearts have been purified by faith. Read Acts 15:8-9, which is the very first Church Council. Peter declares that whether Jew or Gentile, if we receive Christ, our hearts are pure. After we die, there is no further opportunity to decide that you want to go to heaven; we must decide in this life what we will do with Christ. Accept Him or reject Him. God bless.
