Some trust in chariots, and some in horses, but we will remember the name of the LORD our God.
— Psalm 20:7
Our trust should be in the Lord and not in the tools or weapons at hand. Joshua learned this lesson.
God told Joshua, “Have not I commanded you? Be strong and courageous. Do not be afraid or dismayed, for the Lord your God is with thee wherever you go” (Joshua 1:9). The Lord told Joshua that he was to be strong and courageous. To face the giants? No. Rather, he was to be strong and courageous “to observe to do everything I have commanded you, and this is so important that you are to meditate upon it day and night” (paraphrase of Joshua 1:7-8).
God did not say, “When the Hittites come out, you want to use the spear, so you should have your spears. They should all be seven feet long, sharpened to a point. When you are facing, however, the Canaanites or the Philistines, the sword is more effective.” He didn’t tell Joshua how to deal with those problems at all.
Why? Because God was going to deal with them. “No man shall be able to stand before you,” Joshua was told. He put his faith in the Lord; he obeyed Him. And the rest is history.
