In Joshua 24, Joshua is now 110 years old and he knows it's time for him to die so he's giving his last address to Israel. He gives them some advice and it really falls into three charges. You need to be confident in God. You need to be courageous for God. And you need to be committed to God. These were the same three charges that God gave Joshua way back in Joshua 1 when Joshua took over leadership of Israel. Now, Joshua is passing those same charges on to the nation.
Four times Joshua draws their attention to “the Lord your God.” Remember that it was the Lord your God that drove out the enemies. It was the Lord your God that gave you the land. Joshua is saying, “Listen, I'm about ready to die but you're going to be fine because I'm not the one who's given you the victories. It's been God. And the same God who gave you the victories in the past will continue to be with you. Their confidence should be in the God who gave them all of these amazing victories. Folks, listen, God buries His leaders but His work always continues. We can't put our confidence in any one person or any one leader. Our confidence must always be in God.
