After God did amazing things to enable Israel to enter the Promised Land, He stopped them in their tracks and told them to be circumcised. Why? Because they needed to honor that miracle with definite commitment to Him before He would fight their battles coming up.
So it is with us. We follow God, ask for and see Him do miracles for us. But if we hope to see a revival in our churches and across America, we need to be circumcised in our hearts - visibly serving the LORD, not the world. It will be painful, costly, and well-rewarded.
