Paul is telling us and the Philippians that whatever he has suffered, whatever he has lost, it is nothing compared to what he has gained in Christ. Whenever we make changes in our lives, we lose as well as gain. When we move on from high school to the work force or to college, we will gain friends and lose friends.
If we change jobs, we may even lose the ability to see our families as often as we had been able to do. If we change our religion or our religious habits, we also may lose friends or even connections with our family members.
Christianity requires changes in our lifestyle if we are to be faithful to God's will. Doing the right thing becomes more important than hanging out with friends who can lead you in a different direction. Attitudes can change and your behavior with them.
You're no longer the fun person who likes the dirty jokes who doesn't complain about foul language, who won't go to the x-rated movies, or engage in other activities contrary to Jesus' law of love.
What is lost, however, is so much greater, as Paul tells us. Faith gives us trust in God's promises, freedom from fear of the future. We have been made acceptable to the Father through Christ.
