The Lord commissioned Joshua saying: Be strong and courageous
“This Book of the Law must not depart from your mouth. Meditate on it day and night so that you may act carefully according to all that is written in it. For then you will make your way successful, and you will be wise. Have not I commanded you? Be strong and courageous. Do not be afraid or dismayed, for the Lord your God is with you wherever you go.” (Joshua 1:8-9)
God commissioned Joshua to the great work of leading His people to take possession of the Promised Land. This would involve leading the army in a series of battles against sometimes fierce opponents protected by well-fortified city walls. But the battles belonged to God, and He promised Joshua victory if he strictly and carefully followed His instructions. Joshua must hold God’s Word foremost in his thoughts at all times.
The Lord exhorted Joshua to stay strong and courageous. The Great Jehovah issued the marching orders, and vowed to remain present among them. Jehovah faithfully keeps His promises; He powerfully performs, and supplies everything required for success.
