Joshua 5:2 (NIV)
2 At that time the LORD said to Joshua, "Make flint knives and circumcise the Israelites again."
Right before the Israelites moved into their Promised Land, the Lord commanded the whole nation of them to be circumcised. This ‘cutting away’ of the flesh is symbolic for us of embracing the cross, and dying to our agenda, and our way of doing things – to embrace His agenda, and His way.
The Israelites had already been circumcised before, but the entire generation that had been circumcised had died in the desert. This was a new day, and a new generation. But they couldn’t rest on what the previous generation had done – they had to go through the same process themselves.
In our day, God is raising up a new generation that will advance the Kingdom of God far beyond what previous generations have done. To a large extent, we get to ‘stand on the shoulders’ of battles won by the previous generation. But this generation must come to the cross themselves, and embrace the death that leads to life. Only then will we be prepared and ready to enter into the fullness of what God has for us!
