Philippians 1:22-25

But if I live on in the flesh, this will mean fruit from my labor; yet what I shall choose I cannot tell. For I am hard-pressed between the two, having a desire to depart and be with Christ, which is far better. Nevertheless to remain in the flesh is more needful for you. And being confident of this, I know that I shall remain and continue with you all for your progress and joy of faith
