He actually walked around an area of downtown Chicago claiming every place the sole of his foot touched for a Bible school to train young people in the Word. Today Moody Bible School stands on that site. God commands us to claim a possession for Him. . Joshua needed the encouragement of the Lord, as we all do. If he was to be successful, Joshua needed to know the source of his strength and be conditioned for success.
All believers have a similar promise in Matt.
This command is repeated in verses seven and nine. Being strong in the Lord and courage and confidence of success arise out of our study of the Word of God. Two spies were sent out from the camp at Abel-shittem, which was about the enemy and his territory. When Joshua sent the spies into the land he was demonstrating that delicate balance between trusting the Lord and moving ahead to discern the Lord's will. But to have sat tight when that blessing has been promised would have been equally wrong.
