Paul reminds us that “our citizenship is in heaven”, that faith is a critical pre-requisite for righteousness, and that we, like Paul, should consider any confidence in the flesh as worthless, choosing instead to become like Christ in his death, that by any means possible we too may “attain the resurrection from the dead.”
We’ve been given a great gift, “the peace of God, which surpasses all understanding”, which is a cause for rejoicing. We have no need to be anxious for the things of this life, “but in everything by prayer and supplication with thanksgiving let your requests be made known to God.” It’s up to us to follow Paul’s example, and the God of peace will be with us as He was with Paul.
