Deuteronomy 31:19-29

Having been warned of the dark future which Israel was making for herself; Joshua is urged in the meantime to be strong (v. 23). For he did not draw his power from the people but from the LORD. No doubt, dear young people, you have come across many weaknesses and failings amongst the Christians whom you know. Your elders are a long way from always setting you a good example. The meetings which you attend sometimes only give you a little bit of teaching. Is there not often something which discourages you? By looking to people it cannot be any other way. But if your look is directed towards Jesus you will not be at all deceived. In Him are inexhaustible supplies of grace and perfect things which are capable of meeting all our needs.
Moses, Joshua and Paul . . . knew what would become of their work down here. "For I know that after my death ye will utterly corrupt yourselves . . . " said Moses (v. 29). "For I know this, that after my departing shall grievous wolves enter in among you . . .", announced Paul (Acts 20:29). But they also knew whom they had believed, and they trusted in His power (2 Timothy 1:12).
