A) Yes I believe in heaven because as a follower of Christ( Christian) the bible made us to understand that there is heaven and there is hell. Every follower of Jesus Christ must believe there is heaven because the end point of every believer is to make heaven after spending time on earth here because heaven according to the bible is a paradise.

B) Heaven is my goal after living a good life on earth and I am hoping to make heaven by the grace of almight God because my works alone can't take me their neither will my deeds take me but his grace and mercy will take me to a place where there is no hard labour before eating, heaven is my ending point after life and I will definitely be there some day.
