But this isn’t the kind of suffering that Paul is talking about. Jesus says, “My power is made perfect in weakness.” No one is proud of being weak. No one brags about being cut from the varsity team, or about being passed over for a promotion. No one boasts of needing pills to keep themselves even, or of the late night binges of a pornography addiction. No one is proud of not knowing how to handle conflict between their parents, or what to do when their kids just won’t listen. Paul is talking about the embarrassing kind of suffering, the suffering of being helpless and feeling weak. This is just where Christ left Paul, just where Christ called him to remain.
That’s because it is only in our weakness that the gospel has real power. In Romans 1, Paul says that the gospel is the power of God for salvation. Jesus said that he did not come to tend to the healthy but to the sick and to the lost. Salvation necessarily means admitting you’re weak, admitting that you can’t find your way, that you can’t fix the problem. It means admitting that you just can’t stop, and that the situation is out of control. Salvation is for those who need saving.
This salvation, too, is not a one-time event. Yes, we are united to Christ once for all time—our final acquittal cannot be revoked. But salvation is also a moment-by-moment, existential dependence upon the grace of God in Christ. We are never free of our need of him. This is why all are equal in Christ, and why there is no room for boasting.
