'How do you respond when God's plan doesn't make sense'?

Joshua 6:1-5 New International Version

6 Now the gates of Jericho were securely barred because of the Israelites. No one went out and no one came in. 2 Then the Lord said to Joshua, “See, I have delivered Jericho into your hands, along with its king and its fighting men. 3 March around the city once with all the armed men. Do this for six days. 4 Have seven priests carry trumpets of rams’ horns in front of the ark. On the seventh day, march around the city seven times, with the priests blowing the trumpets. 5 When you hear them sound a long blast on the trumpets, have the whole army give a loud shout; then the wall of the city will collapse and the army will go up, everyone straight in.”
