Jesus makes reference on how important it is to live your life the way God wants us to live. In this instance some people followed Him after He journeyed overnight to another location. Jesus perceived their wanting another meal, after all, who would not like a second meal if the first was pleasing and, quite frankly, a bit of a miracle? He uses the situation as a springboard to highlight the importance of listening to God in our daily life. Eating is important — we can’t live too well without it. It’s just that living in the Kingdom is also necessary and healthy for us.
Paul correlates eating and the Kingdom of God in Romans 14:17. The Holy Spirit’s entanglement with righteousness, joy, and peace in his comparison means more than the eating of food.
Take time to truly nourish your soul: build some time with Jesus, set apart some time to pray, listen. Chew the cud on God’s Word. Consider Luke 16:13 (and surrounding verses). You either serve God, or you are tied to the tethers of this world.
