Jehovah's Witnesses : regarding Abraham and the Heavenly Hope?

There was a reason why those who died before Jesus, such as David, John the Baptist, and other men of faith, did not go to heaven. They died before Jesus inaugurated the way or possibility for humans to be resurrected to heavenly life. The apostle Paul wrote that Jesus, like a forerunner, “inaugurated . . . a new and living way” into heaven.—Hebrews 6:19, 20; 9:24; 10:19, 20.
