Philippians 2:12-16a

Paul calls us to selfless unity (1:27-2:4) and shows the example of Christ (2:5), who gave Himself up in deference to the Father (2:6-8) and did not exalt Himself (but the Father did!) (2:9-11). Then, in 2:12, Paul signals a conclusion to this section with the words "so then." Here, he harkens back to the ideas of 1:27 and adds two commands: one serious and one practical.

Philippians 2:6-11

As Paul exhorts the Philippian church to Christian unity (1:27-2:4), he calls them to selflessness. This is because unity always requires the loss of self for the benefit of the group. It is at this point that Paul gives us the apex of all examples of selflessness—Christ. He calls us to tune our minds to His actions of self-denial, self-sacrifice, self-humiliation and non-self-exaltation.

Philippians 1:27-30

Paul states in 1:24-26 that he anticipates his release and that he will come to minister again in Philippi. But given some uncertainty as to when he will arrive, he focuses their attention on one purpose: "Only [this is the singular focus] conduct yourselves in a manner worthy of the gospel of Christ" (1:27a). He calls them to live worthy of the gospel. Now, the Philippians weren't newbies in the Christian faith. They engaged in the defense and confirmation of the gospel (1:7). They supported the gospel ministry (1:5). And they had done this for 10+ years! Do they really need such an elementary instruction? They did, because they lacked a crucial area of this worthy conduct: unity.
