The Cosmic Centerpoint

Behold, now is the favorable time; behold, now is the day of salvation. --2 Cor 6:2

Paul Barnett, in what is my favorite commentary on 2 Corinthians for theological reflection:

This verse is arguably the key verse of the apostolic excursus (2:14-7:4) and, indeed, of the entire letter. . . .

Powerfully and explicitly Paul declares that the world and history have been overtaken by God, that God's 'time,' his 'say of salvation,' has 'now' arrived. Everything that Christ has done as the cosmic, soteriological, and eschatological centerpoint is now affirmed by the word that covers all the ground of vv. 14-21--salvation.

--The Second Epistle to the Corinthians (NICNT), 318
