Worthy of the Sacrifice.

Philippians 1v27-28
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, and not frightened in anything by your opponents. This is a clear sign to them of their destruction, but of your salvation, and that from God.

Paul is laying it straight here. We must live a life worthy of the sacrifice by Christ and in doing so have no fear showing our complete faith and trust is founded upon the creator of all things which is far greater than anything of this world.
