Didache (1st Century) 3:8:
Accept whatever happens to you as good, in the realization that nothing occurs apart from God.
Testaments of the Twelve Patriarchs (1st or 2nd Century), Testament 11, Paragraph 2:
For He will in no wise forsake them that fear Him, neither in darkness, nor in bonds, nor in tribulations, nor in necessities. For not as man is God ashamed, nor as the son of man is He afraid, nor as one that is earth-born is He weak, or can He be thrust aside; but in all places is He at hand, and in divers ways doth He comfort, departing for a little to try the purpose of the soul.
