In Philippians 3:3 Paul says that all true Christians worship in the Spirit, glory in Christ, and put no confidence in the flesh. This is talking about humanity in general. Flesh is a reference to all you are as a human being. Mankind is hopeless and in desperate need of rescue. Flesh is cursed and doomed apart from divine intervention. Awareness of this reality slips away when religion comes to town. It says deep inside man is good and just needs to work harder. Over time we entertain thoughts that we matter. We attempt to build up credit with God and eventually earn salvation. The reason people don’t want to embrace the free grace of the Gospel is that it requires cashing out. It’s too easy, and it calls Christians to forfeit all hope of credit. No trophy. No ribbon. No patch for your vest. No recognition. Christ demands waiving your involvement in the trial. He alone pleads your case based on his merit. You remain silent. Rescue comes from what he did in the flesh. Like the hymn, I need no other argument, I need no other plea, it is enough that Jesus died, and that he died for me.
