this quote from Joel Beeke on ligonier’s blog is a great way to explain the christian walk:
The way to godly living is surprisingly simple: we are to walk with God in His appointed way (Micah 6:8), diligently using the means of grace and the spiritual disciplines, and waiting upon the Holy Spirit for blessing. Note that godly living involves both discipline and grace. This emphasis upon duty and grace is fundamental to Reformed, experiential ideas about godly living. As John Flavel wrote, “The duty is ours, though the power be God’s. A natural man has no power, a gracious man hath some, though not sufficient; and that power he hath depends upon the assisting strength of Christ.”
emphasis added.
