Joshua’s words went out to “the chosen generation.”
God had waited until all those who were stiff-necked and rebellious had grown old and died. That younger generation would go forth and inherit the promises. After they crossed the Jordan, God told Joshua to “make flint knives for yourself, and circumcise the sons of Israel again the second time,” (Josh. 5:2). The older generation was circumcised, but the younger generation had not been. They were to bear the mark of covenant in their flesh before God would take them any further.
Circumcision speaks of sanctification of the flesh. It is cutting away dead things and hidden sins. You can look good publicly, raising your hands, giving your offerings, praying and even fasting, but all the while hiding deadly sins. You are sanctified by the blood of Jesus when you first accept Him as your Lord and Savior, but over time, complacency and hidden sins can creep into your heart.

You can just start drifting, and you let your standard down. Paul explained this clearly to the Galatians:
Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God (Gal. 5:19-21).
The blessing of sanctification brings with it the promises of God’s covenant and life in the Spirit:
The fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control. Against such there is no law. And those who are Christ’s have crucified the flesh with its passions and desires. If we live in the Spirit, let us also walk in the Spirit. Let us not become conceited, provoking one another, envying one another (Gal. 5:22-26).
Fasting sharpens the blade and sharpens the Word in your heart and in your mouth, allowing you to cut away the dead flesh and hidden sin as you set yourself apart for God.
What About You
What if you set yourself to diligently seek the Lord, sanctifying yourself with a fast and journey back to the spot where it all began—where He saved you, set you free, filled you with His Spirit and called you out?
I actually physically traveled to that spot, but if you cannot do that, you can go back mentally. You can recall the ancient landmark, that same simplicity, innocence and dedication with which you first responded to His voice.
God wants you to ask Him for—believe Him for—things that are bigger than yourself. I cannot just float through life. I can’t kick back and wait for retirement. I have too much promised! I want to reap the harvest.
The children of Israel had made it through the wilderness. They had stopped eating manna and had begun to eat the good fruit of the land. They lived along a river, and they could have easily set up trade with those from the big city of Jericho, but that was not their destiny.
Fasting will bring you into destiny. Fasting will bring you into alignment with God’s plan for your life. Just as Joshua called the children of promise to sanctify themselves—I believe that, likewise, your “tomorrow” is just around the corner. God is going to do wonders in your life, leading you places you have never been before. Now is the time to fast, to seek God diligently, to sanctify yourself, to discern God’s priorities, and to walk in His promises. Go for it!
