Philippians 1:22-24

If, however, it is to be life here and I am to go on living, this will mean useful and productive service for me; so I do not know which to choose [if I am given that choice]. But I am hard-pressed between the two. I have the desire to leave [this world] and be with Christ, for that is far, far better; yet to remain in my body is more necessary and essential for your sake.
