The generation that made it through the 40 years in the wilderness were left with a decision: would they obediently follow after the Lord and reinstate the circumcision or would they continue down the path the previous generation had led them down and forsake God’s command?
They chose the leading of the Lord, rightfully so…even though they hadn’t been a left with a great legacy to follow after they realized that they were ultimately responsible for the decisions that were theirs to make.
There is no such thing as “the blame game” when it comes to the Lord. He has given each of us opportunity to serve him. We decide for ourselves how we will respond.

Joshua 5:2-9
