Paul, an apostle of Christ Jesus by the will of God, and Timothy greet the church of God in Corinth and all the saints in Achaia, wishing them grace and peace. Paul blesses the Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction so that we may comfort those in any affliction with the comfort we ourselves receive. The sufferings of Christ abound in them, and so does their comfort.
Paul tells of the affliction he suffered in Asia: he was so utterly burdened beyond his strength that he despaired of life itself. He felt he had received the sentence of death, so that he would not rely on himself but on God who raises the dead. God delivered him and will deliver him, and he asks for the Corinthians' prayers so that many may give thanks on his behalf.
He boasts in the testimony of his conscience: he has conducted himself in the world, and especially toward them, with the holiness and sincerity of God. He explains that he wanted to visit them twice, on the way to Macedonia and on the way back, but changed the plan. He did not do so lightly or like someone who says Yes and No at once. God is faithful, and Paul's word has not been Yes and No, because Jesus Christ was not Yes and No but Yes. All God's promises find their Yes in him, and so through him we say Amen to the glory of God. God has established them with Paul in Christ, anointed them, sealed them and given the Spirit as a guarantee.
Paul calls God as witness: it was to spare them that he did not come again to Corinth. Not that we lord it over their faith, but we work with them for their joy, for in their faith they stand firm.
