Phillipians 1:27 Meaning? your opinion on this particular verse? what is it saying? Thanks!?

Phillipians 1:27 Only let your manner of life be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of you that you are standing firm in one spirit, with one mind striving side by side for the faith of the gospel-so I'm 13 and I cam across this and was wondering what it meant as a verse in the bible the meaning thanks! -from Caleb 13yrs old
