The porcupine’s very survival relies upon its continued connection to other porcupines (mostly family). The body of Christ mirrors that connection commitment. It’s imperative that we Christians stand together in order for the body of Christ to survive as a collective unit. And, individuals within that collective unit feed off that body that gives them support and edification. Your biological family can often cause you pain, but you don’t give up on them (hopefully). Ditto that with your relationship the the body of Christ with one major difference: severing your biological family unit doesn’t have the eternal consequences that breaking with the body of Christ would!
