2 Corinthians 1:12-24

v12-14: When a believer in Christ is seen to be living lives that are "holy, upright, and without blemish" (in the sense of being above reproach rather than sinless), it is a cause for rejoicing.  Members of a local church should rejoice when their leaders are seen to behave in this way, in the same way that leaders do when members are living godly lives.

v15-24: All of God's promises are "Yes" and "Amen."  This is because they are the promises of God who cannot lie; they are made in Christ Jesus who is the Amen, and the true and faithful witness; and they are confirmed by the Spirit of truth who strengthens the faith of a Christian in them.  "The truthfulness of God, the mediation of Christ, and the activity of the Spirit are all committed to see that the promises will be certain to all Christ’s descendants, and their fulfilment will be to the glory of God."
