How do you make gains in life? Rather than give specific behaviors, the Apostle Paul is going to first describe a specific faith. Without the faith Paul describes, any so called gains would be rendered useless.
However, because the human heart is so drawn to religious performance in order to merit righteousness, resting in the righteousness that comes from faith is extremely difficult. But once we finally stop our attempts at self-righteousness, the power of the resurrection of Jesus can become active in our lives.
