Some believers, though they have faith and hope for Heaven, do not share and proclaim the gospel. What would you do if you saw a person sleeping in a blazing house? Even if you dont know him, wouldnt you still try your best to save him? Then how can you sit still doing nothing though you know your beloved ones havent accepted Jesus Christ and will fall into the unquenchable fire of Hell? Evangelizing people is not a matter of choice but what we must do (1 Corinthians 9:16).
