“Only be strong and very courageous, being careful to do according to all the law that Moses My servant commanded you. Do not turn from it to the right hand or to the left, that you may have good success wherever you go. This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.” – Joshua 1:7-8
Three times, the LORD told Joshua to be strong and courageous. In verses 7 and 8, He followed that charge with a command, to obey the law and to meditate on it day and night. He used the word, torah, which means, instruction. It includes the law, but it also includes covenant history. God joined His promise to His commands: Then you will make your way prosperous and you will have good success.
When Joshua faced the fortified cities of Canaan, he would be tempted to believe that victory depended on his strategy, or on Israel’s military power. So God commanded him to meditate on His torah, to bolster his faith. In effect, He said, Read My Word with deep concentration; read it to yourself; and believe that it is for you. Then you will make your way prosperous, and then you will have good success. In other words, The salvation of My people depends on your faith and your obedience, Joshua.
This is what He demanded of our Savior. And this is the gospel: He was perfectly obedient.
“He humbled Himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted Him and bestowed on Him the name that is above every name, so that at the name of Yeshua, every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.” (Philippians 2:8-11)
