Joshua 1

God speaks to His faithful servant: "Be strong and courageous." 
Why can he do this? God's promises still stand. God will be with His faithful servant.
How can he do this? Meditate on God's word so that you will obey God's word so that you may be prosperous and successful (in carrying out God's plan).

God's faithful servant speaks to God's people: "Go in and take possession of the land the Lord your God is giving you for your own."
How can they do this? Keep trusting God's promises and make every effort to enter the land. (God's sovereign plan to give the land to his people invites human action - it does not mean they/we should be passive).
Remember God's commands and carry them out faithfully. 
Help the rest of God's people.

God's people reply to His faithful servant: "Whatever you have commanded us we will do."
How do they do this? By trusting in the Lord's servant, because God's promises to His servant are true and still stand.

Joshua is a foreshadowing of Jesus, God's servant. How will we respond to Jesus? Will we respond to Jesus like the Reubenites, the Gadites and the half-tribe of Manasseh?
