The Bible is the only book in all the earth that does teach a general resurrection of the dead. In the first place, it sets forth that the dead are dead and not alive. Ecclesiastes 9:5, "For the living know that they will die, but the dead know nothing..." Because they are dead, a resurrection is necessary to make them alive. If alive already, there would be no need for a resurrection. The Scriptures teach that the entire race was condemned to death because of Adam's transgression. (1 Corinthians 15:21,22; Romans 5:12,18,19)
In the following Scriptures it is declared in unmistakable terms that Jesus Christ, as the Savior of the world, died for "all"," every man." (1 Timothy 2:5, 6; Hebrews 2:2,9; 1 John 2:2) This last citation shows, beyond all controversy, that Christ is the "propitiation" --satisfaction--not only for our sins, the Church's sins, but also for the sins of the whole world. Jesus's death guarantees a resurrection for all! "...the hour is coming in the which all who are in their graves shall come forth at the voice of the Son of man..." (John 5:28,29). The righteous will be immediately raised up to life, while the evil (the vast majority of mankind) to a gradual raising up (resurrection) by judgment, education, and blessings. The Apostle elsewhere affirms a general resurrection. (See Acts 24:15)
