It has been a couple of years since I have read Philippians. What a tremendous book it is though. Here are a few key things I take from the first chapter:

Celebrate the body of Christ, both giving and receiving encouragement.

Pray for our fellow Christians, realizing that we all fall under the same mantle, and that we all share common goals.

If folks want to be critical of you, that's okay. Just as long as they are working to build the Kingdom, the same as you. There may be differences in opinion as to how that is done but the end result must be our focus.

We are all to be bound to Christ. The more pain we feel in this world, to a large degree, the more bound to and more boisterous we will be for our Savior.

We must die to our selves if we are going to live for Him.

Keep fighting the fight. Adversity will come our way. Paul had more than his share so he speaks from experience. Keep fighting; in the end we will all stand together.
