In the previous couple of verses, Paul expressed his desire to boast about the faith of the Philippian believers. As he finishes this paragraph in this week’s passage, you can see the urgency in his wish.
Take a look at this week’s passage in Philippians 2:17-18:

Paul uses imagery here that is very vivid. He compares his life to being poured out like a drink offering. It is generally believed that he is speaking about his own forthcoming death. It is doubtful if he means an execution, because in verse 24, he expresses hope that he will soon be released.
That means that his terminology here is more along the lines of “even if.” He has run the race. He has labored. And he is willing to die if necessary for the sake of the gospel.
He uses an Old Testament image as a means to illustrate this. A drink offering was something that accompanied a sacrifice, and was to be poured out on the altar, or at the base of it (See 2 Kings 16:13 for an example). In this case, the sacrifice stems from the faith of the Philippians, and Paul is willing to be the drink offering partnered with that sacrifice, if necessary.
It is noteworthy to remember that a drink offering was not worth anything on its own. It was to always accompany a regular sacrifice. What Paul is implying here is that the faith of the Philippian believers is what makes his offering valid. Without their faith, his efforts are in vain.
