“For to this end also I wrote, so that I might put you to the test, whether you are obedient in all things.”
(2 Cor. 2:9)
It’s a test all churches face today, too. Either we will respond obediently to the written words of the apostles, or will we compromise and require divine chastening, or worse.
Paul had written a letter only a few months earlier expressing how the church ought to respond to a man who had sinned among them – and against Paul. The letter required obedience to Christ’s teaching in Mat. 18 on dealing with a sinning brother. This was Paul’s training ground for the church – to see if they will obey the word written by an apostle.
It’s a critical point in every church’s maturity and stability – to learn to respond to the apostolic Scripture obediently.
