I've been looking at different parts of Philippians today, in a couple of different translations. I'm hoping to start learning basic New Testament Greek at some point in the new year which I'm really up for at the moment. I'm aware ancient Greek isn't exactly the easiest language to 'pick up', as it were, but am willing to give it a shot!
The two passages that have stood out so far have been in chapter 2, verses 1-4 which the NIV has thus:

"If you have any encouragement from being united with Christ, if any comfort from his love, if any fellowship with the Spirit, if any tenderness and compassion, then make my joy complete by being like minded, having the same love, being one in spirit and in purpose. Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interests of others."

Just reading that helps me to have a clearer picture of what Christian love is, or can and should be. People often talk about 'service or a servant-heart', but reading that passage reminds me what it might look like in practice. We aren't just to treat a select group of good friends with love and compassion and care (words that, even as I write them, seem so stripped of meaning and divorced from the concept that they indicate) as Jesus says in Matthew 5:46 and Luke 6:32-33 (both of which state something very simillar), but to act towards all people that we come into contact with with love and generosity.

Christian unity, human unity, are nice concepts that can be neatly packaged, but putting them into practice is what really counts. I've always kinda felt that that works best on whatever level you find yourself at; it isn't just about having some kind of massive 'ministry', but doing something simple to make someone else's life even slightly better. I guess it's about being aware of the small things, as well as the big; it's no good helping out at a local mission and then coming home and treating your family or whoever you live with badly; it's no good being impeccably polite to people at a Missions Week event and then being dismissive of that coursemate you'd rather not spend time with today.
