We share how God used Philippians 4:13, to rescue Oliver Cromwell from an overwhelming depression at losing his son. We continue to explore the truth that God lives inside us, and wants to strengthen us from within, by infusing and satisfying our souls with His life and peace, this being the secret that Paul discovered for living a life of contentment. This is a life of faith, so we also discuss faith in God and the faith of God and the gift of faith.
