You have to see the entire passage in context to understand it:

(Philippians 1:15-27 NIV) It is true that some preach Christ out of envy and rivalry, but others out of goodwill. {16} The latter do so in love, knowing that I am put here for the defense of the gospel. {17} The former preach Christ out of selfish ambition, not sincerely, supposing that they can stir up trouble for me while I am in chains. {18} But what does it matter? The important thing is that in every way, whether from false motives or true, Christ is preached. And because of this I rejoice. Yes, and I will continue to rejoice, {19} for I know that through your prayers and the help given by the Spirit of Jesus Christ, what has happened to me will turn out for my deliverance. {20} I eagerly expect and hope that I will in no way be ashamed, but will have sufficient courage so that now as always Christ will be exalted in my body, whether by life or by death. {21} For to me, to live is Christ and to die is gain. {22} If I am to go on living in the body, this will mean fruitful labor for me. Yet what shall I choose? I do not know! {23} I am torn between the two: I desire to depart and be with Christ, which is better by far; {24} but it is more necessary for you that I remain in the body. {25} Convinced of this, I know that I will remain, and I will continue with all of you for your progress and joy in the faith, {26} so that through my being with you again your joy in Christ Jesus will overflow on account of me. {27} Whatever happens, conduct yourselves in a manner worthy of the gospel of Christ. Then, whether I come and see you or only hear about you in my absence, I will know that you stand firm in one spirit, contending as one man for the faith of the gospel
