In verse 1-3 of this passage Paul speaks about the life we are all saved from - a life of self-centredness - a life of boasting in ourselves and what we do. Then, in verses 8-10 he speaks about the life we are saved for - a life of Christ-centredness - of boasting in Christ and what he’s done. And finally, in verses 4-7 he explains he exactly we can move from the life described in verses 1-3 to the life described in verses 8-10.
