Thoughts on Today’s Text
Given what is revealed about the Corinthians in this letter, this is a preposterous claim. Has the Corinthian church really been transformed by God’s glory? These believers have caused great heartache to the apostle and to one another. Paul admits to a previous painful visit and a tearful letter. Yet, the apostle is certain that the church’s continued existence, in spite of itself, is a sign that God is at work within it.
As preposterous as it may seem, God has called the Corinthians to be God’s church, and God is actively at work transforming the believers from one degree of glory to another (3:18). Paul has faith — not in the church’s abilities to change itself — but in the Spirit’s work within it.
The text is saturated with hope that is firmly planted in God. At the beginning of 2 Corinthians 3, Paul refers to the church as his letter of recommendation (3:2). The believers themselves are the evidence that the Spirit of the living God is active in Corinth (3:3). All that they have and all that they are comes from God (3:4-5). It is Paul’s confidence in God’s work through Christ that undergirds verse 12: “since we have such a hope, we are very bold.”
