For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
~Philippians 3:3
As Christians, we must learn how to transfer our confidence in serving God from our fleshly works over to God as the divine Workman of our souls. This transfer in confidence requires faith in God and our faith grows when we experience what the Sabbath rest is really all about.
