What does it mean that the testimony of Christ was confirmed in the Corinthians?
It means the testimony about Christ was sealed and settled in them, so they lacked no spiritual gift and were enabled for great things while awaiting Christ's coming. Paul adds that Christ will confirm them to the end, blameless—not because they were sinless, but on the basis of grace.
Les explains that the words "confirmed," "sealed," and "settled" mean the testimony of Christ was fixed and secure in the Corinthians. Consequently, they came behind in no gift; they were just as potentially able to accomplish great things as anyone could be, waiting for the coming of the Lord Jesus Christ. Les points to I Corinthians, verse 8, where Paul says Christ also shall confirm you unto the end, that you may be blameless. Les calls this mind boggling because the Corinthians had failures and weaknesses, yet if the Lord had come within a day or two after they received this letter, Paul says they would stand before Him blameless. They were not blameless in themselves; God could do this on the basis of grace. Les also recalls that he had alluded to eternal security for the true believer, and a gentleman from Oklahoma called, a little upset, asking how he could do that.
