Question: How many are in, or will be in, heaven?

Answer: All who have put their faith in Jesus Christ as Lord and Saviour will be in heaven (Ephesians 2:8-9, Romans 10:9-13)...

    Revelation 5:9
    And they sang a new song: "You are worthy to take the scroll and to open its seals, because you were slain, and with your blood you purchased men for God from every tribe and language and people and nation. (NIV)

    Revelation 7:9
    After this I looked and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and in front of the Lamb. They were wearing white robes and were holding palm branches in their hands. (NIV)

The bottom line... Only God knows the full total (2 Timothy 2:19), but by the verses quoted above we can be assured that the total is exceedingly great and diversified. God's family is a big one! (Romans 8:14-17)
