Heb 3:1 refers to "holy brothers, partakers of the heavenly calling". In Mk 3:35, Jesus says, "Whoever does the will of God, this one is my brother..." Therefore, according to the Bible, whoever does the will of God is a brother of Jesus and a partaker of the heavenly calling. How can this be if the Watchtower Society teaches that only 144,000 people go to heaven?
The truth is, the heavenly calling is by invitation only. Paul explained that the calling does not depend upon the one wishing, but upon God's choosing. That is why the Bible uses the expression "the chosen ones." Jehovah personally chooses those whom he wishes to adopt as sons - even as Paul indicates in the verse cited by referring to the "heavenly calling." A person may wish with all of the heart to go to heaven, but if God does not call a person and draw them into union with Christ then those who merely claim to be called, when they have not truly been called, are mere frauds and charlatans and deluded fools. And there are masses of persons who profess to be called to heaven, who boast of prophesying in the name of the "Lord," but in the day of judgment Christ will say to them: "Get away from me, you workers of lawlessness."
According to the Bible only 144,000 will master the new song and join Christ in heaven. The vast majority of Jehovah's Witnesses, instead of presuming to be called ones, embrace the hope of everlasting life on earth. The presumptuous and untaught will lose out entirely because of their refusal to accept salvation on Jehovah's terms.
