Note 18 at Phil. 1:24: Paul had a vision of heaven that made him long to go there. Yet he was remaining in his physical body for the sake of others. Most people are clinging to this physical life for selfish reasons. Paul was clinging to it for totally unselfish reasons. Only when we lose our life (die to self and live for Christ and others) do we truly find out what life is all about (Mt. 10:39).
