John 16:7Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
Acts 20:29-31For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them. Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
Philippians 1:22But if I live in the flesh, this is the fruit of my labour: yet what I shall choose I wot not.
Philippians 1:25-26And having this confidence, I know that I shall abide and continue with you all for your furtherance and joy of faith; That your rejoicing may be more abundant in Jesus Christ for me by my coming to you again.
