“Whoever heeds discipline shows the way to life, but whoever ignores correction leads others astray.” (Proverbs 10:17, NIV)
In what things do we display “discipline”?
Is it in the practice of unceasing prayer? Is it in the practice of hospitality? Is it in the practice of humility? Is it in the practice of valuing time in worship with others?
Know it or not; like it or not; our children, our peers, our co-workers, our neighbors, and even the casual stranger are watching us live our lives. Do they see us display a discipline that “shows the way to life”?
Conversely, when we ignore discipline and correction, our lives are on a path that leads nowhere — and know it or not; like it or not; others follow.
Heeding the discipline of healthy and holy habits not only delivers life to us, but it delivers life to others, as well. – Luther
