VM, the one about the sheep having to call out before the shepherd looks for them is in a WT study article:
w02 3/1 p. 16 How Precious Is the Truth to You? ***13 In Scotland some young lambs were grazing in a pasture when one of them strayed to the side of a hillock and tumbled onto a ledge below. It was uninjured, but it was frightened and unable to climb back. So it started to bleat plaintively. Its mother heard it, and she too began to bleat until the shepherd came and retrieved the young lamb.
14 Notice the sequence of events. The lamb called for help, the ewe added her voice to its cries, and the alerted shepherd sprang into action to rescue it. If a very young animal and its mother can sense danger and immediately call for help, should we not do the same when we stumble spiritually or face unexpected dangers from Satan?s world? (James 5:14, 15; 1 Peter 5:8) We should, especially if we are lacking in experience either because we are young or because we are relatively new in the truth.
