God doesn't just tell Joshua to suck it up, don't be afraid and get some courage. He tells him you don't have to be afraid and you can be strong and courageous because, "I will not leave you or forsake you." (Joshua 1:5b)
God often calls us to big and scary things. He often lets us see glimpses of what's in store and what's ahead can seem frightening. But, if you are a child of God He has given you "a spirit not of fear but of power and love and self-control." (2 Timothy 1:7)
How do we tap into this spirit of power that Paul talks about? How can we face the challenging tasks of life with strength and courage? Psalm 31:24 says, "Be strong, and let your heart take courage, all you who wait for the Lord!"
Ahh...so there's a catch. Yes, God is with us always and He give us the power to be strong and courageous for the big tasks of life. But, in order to experience His constant presence and be sustained by His power and strength in order to be courageous, we have to "wait for the Lord." God tells Joshua in 1:7-8, "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."
So, our ability to be successful in facing the challenges of life is directly related to our time spent meditating on and obeying His Word. Psalm 1:1-3 says:
"Blessed is the man
who walks not in the counsel of the wicked,
nor stands in the way of sinners,
nor sits in the seat of scoffers;
but his delight is in the law of the Lord,
and on his law he meditates day and night.
He is like a tree
planted by streams of water
that yields its fruit in its season,
and its leaf does not wither.
In all that he does, he prospers."
So, what challenges are you facing this day, week, month or year? Are you excited, afraid or timid? God wants you to know, as He wanted Joshua to know, that He will never leave you or forsake you. He wants to empower you to be strong and courageous for the task He has set before you. Will you go to Him, be as a tree planted by streams of water, meditating on His Word knowing that the source of all strength and courage comes from Him?
be not dismayed, for I am your God;
I will strengthen you, I will help you,
I will uphold you with my righteous right hand."
(Isaiah 41:10 ESV)
