The books of Philippians and Colossians are letters written to the early church in the cities of Philippi and Colossae by the apostle Paul. Philippians may be summed up in one word--joy: joy in living, joy in service, joy in fellowship, and joy in rewards. Jesus Christ is the secret of our joy. Colossians proclaims Christ as the Head of the body. He is our life, and we are complete in Him. Paul urges us to be rooted in Jesus, to be built up in Him, to be hidden in Him, and to present Him to the world.
