“Be strong and courageous, for you are the one who will lead these people to possess all the land I swore to their ancestors I would give them. Be strong and very courageous. Be careful to obey all the instructions Moses gave you. Do not deviate from them, turning either to the right or to the left. Then you will be successful in everything you do. Study this Book of Instruction continually. Meditate on it day and night so you will be sure to obey everything written in it. Only then will you prosper and succeed in all you do. This is my command—be strong and courageous! Do not be afraid or discouraged. For the Lord your God is with you wherever you go.” Joshua 1:6-9 NLT
The LORD talk to Joshua (because he will lead the people to claim the promise land) to “be strong and courageous”. Strong and courageous not because there is an enemy to overcome nor there are walls to be crushed and giants to be slain but because there is a command, a set of instructions from The Book that needed to be known by heart, doing everything written in it in order to succeed, conquer and live in the promised land.
We live at a time where these set of instructions are tested for its reliability, truthfulness and applicability. I believe that God is constantly reminding His people to be strong and courageous, adhering and carefully reading, studying and teaching the word of God in faithfulness and truthfulness because only by that we are assured of victory. We will not deviate from either right or left if we make the bible as the absolute source of authority. If all the preaching and teaching we hear and deliver came from our faithful study of the word of God through prayer and power of the Holy Spirit, we can fulfill the God intended purpose and eventually conquer and live to the promised land which the Lord promised to our ancestors.
Come to think of it:
GOD is not concerned on who the enemy is nor how powerful they are but on how you will obey and love His word because our success depend on it.
