warning against spiritual malnutrition

To look at Christ is to live, but for strength to serve him you must "come and dine." We labour under much unnecessary weakness on account of neglecting this precept of the Master. We none of us need to put ourselves on low diet; on the contrary, we should fatten on the marrow and fatness of the gospel that we may accumulate strength therein, and urge every power to its full tension in the Master's service. -- Charles Spurgeon, Morning and Evening
