The context of John 11:26 is the death and resurrection of Lazarus.  Martha expresses understanding of Jesus’s words without asking ‘why did my brother die since he was a believer?’ This indicates a deeper meaning is meant. Some English translations add the proper insight to this verse – that those who believe in Jesus will not ultimately die. See Wycliff Bible and Youngs Literal Translation among others.  The Apostle Paul summarizes God’s plan concerning everlasting life in 1 Corinthians 15: 21-26 “For since by a man death came, by a man also came the resurrection …  For as in Adam all die, so also in Christ all will be made alive.  But each in his own order: Christ the first fruits, after that those who are Christ’s at His coming (This word” translated as “coming” in English is the Greek word meaning “presenceHh This refers to mankind during the Millennial Age), then e hands over the kingdom to our God and Father, once he has abolished all rule and all authority and power. For He must reign until He has put all His enemies under His feet. The last enemy that will be abolished is death.”

God’s plan of salvation will eventually secure eternal life to EVERYONE who wishes. Those now faithful will receive a grand heavenly resurrection. While everyone else (who has ever lived) will be rewarded with perfect, everlasting human life. Death will be abolished.

Hebrews 9:27 is in harmony with this concept. Here the Apostle Paul recounts the spiritual, symbolic significance regarding God’s Tabernacle. Scriptures leading up to verse 27 explain that Jesus is our great antitypical High Priest. Verses 24-26: “For Christ did not enter a holy place made by hands, a mere copy of the true one, but into heaven itself, now to appear in the presence of God for us; nor was it that he would offer himself often, as the high priest enters the Holy Place year by year with blood that is not his own. Otherwise, he would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages he has been revealed to put away sin by the sacrifice of himself.”

To interpret verse 27, we need to understand it refers to the annual Atonement Day when the High Priest was subject to death. (See Leviticus 16:11-14.) “And as it is appointed unto the* men (typically the high priests – but antitypically Jesus) once to die, but after this the judgment.” It was Jesus, who was judged and found WORTHY. Jesus entered into God’s presence (the Most Holy in the Tabernacle) with his sacrificial blood.  Ephesians 3:17-19 “…That ye, …may be able to comprehend with all saints what is the breadth, and length, and depth, and height;…And to know the love of Christ, …that ye might be filled with all the fulness of God.”

*Nestle Al and 28 New Testament Greek Text is the most accurate recension, and it has “the.” Translators have omitted the word “the” because it doesn’t agree with their doctrines. However, the even translators for the King James Bible (in the 1600’s) knew the Greek word for “the” was in the manuscripts, and they also refused to translate it. We should never omit and add words to God’s Holy Bible.
