Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him (John 6:27, NKJV).
Some people followed Jesus because they expected Him to work a miracle and feed them. Jesus rebuked this shallow, selfish, faithless view of Him (John 6:26). Jesus contrasted their misguided motive for seeking Him with working for the food that produces everlasting life. He was by no means saying do not work for your daily food (“If anyone will not work, neither let him eat,” 2 Thess. 3:10). Jesus said to be concerned primarily with working for the food that leads to everlasting life. The work God gives us to achieve that result is to “believe in Him who He sent” (John 6:29). Jesus is the “bread of life” in whom we must believe to eat “the living bread which came down from heaven” (John 6:35, 51, 58). By faith, we do so when we receive and obey His words (John 6:63-68). Unbelievers do not trust and follow Jesus; believers do. When we accept and obey His word, we have not earned everlasting life; we have only done a servant’s duty (Luke 17:10). The gospel call is, “You who have no money, come, buy and eat” (Isa. 55:1-3). The question to ponder is, “Why are you seeking Jesus?” To gain some temporary, physical advantage, or to labor “for the food which endures to everlasting life?”
18 And he said to them, “Then are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile him, 19 since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.) 20 And he said, “What comes out of a person is what defiles him.” (Mark 7:18–20, ESV)
The Law of Moses contained dietary restrictions for Israel which distinguished between clean and unclean animals (Lev. 11). Jesus removed those limitations, explaining that food does not defile a person (Col. 2:14-17). Evil that comes from within our heart defiles us (Mk. 7:21-23). Demanding abstinence from certain foods as a way of holiness is apostasy (1 Tim. 4:1-3). Yet, some faiths that forbid certain foods in the name of Jesus. One example is The Church of Jesus Christ of Latter-day Saints, whose Word of Wisdom (Doctrine and Covenants 89) forbids “hot drinks,” which Church leaders have explained means abstaining from coffee and tea (“Vaping, Coffee, Tea, and Marijuana,” New Era, August 2019). Seventh-day Adventists typically follow a vegetarian or vegan diet due to supposed revelations of Ellen G. White (“What Do Seventh-day Adventists Eat?,” seventhdayadventistdiet.com). By contrast, the Bible says that “food does not commend us to God; for neither if we eat are we the better, nor if we do not eat are we the worse” (1 Cor. 8:8). When it comes to righteousness, we must be more concerned about what comes out of our hearts than what goes into our stomachs. “For the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit” (Rom. 14:17).
25 And when they found Him on the other side of the sea, they said to Him, “Rabbi, when did You come here?” 26 Jesus answered them and said, “Most assuredly, I say to you, you seek Me, not because you saw the signs, but because you ate of the loaves and were filled. 27 Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.” (John 6:25–27, NKJV)
These people had seen Jesus miraculously feed five thousand souls the day before, from only five barley loaves and two fish (John 6:1-14). The next day they had traveled around the Sea of Galilee to find Him. They had not followed Jesus out of faith in Him as the Messiah. They were driven by their bellies to seek another meal. Why are you following Jesus? Is it out of faith or convenience? Jesus can give you spiritual food that produces everlasting life, but you must have faith in Him to follow Him according to His will. The Father endorsed Jesus by the miracles He worked. Be sure you are following Jesus for the right reason – for everlasting life – and not to fill a self-serving interest.
15 “There is nothing that enters a man from outside which can defile him; but the things which come out of him, those are the things that defile a man. 16 If anyone has ears to hear, let him hear!” (Mark 7:15-16)
The heart is the spring well from which comes all things both good or evil. Israel was commanded to observe food restrictions under the Law of Moses (Lev. 11). But, what Jesus Christ taught on this occasion made all food pure (Mk. 7:19). The food that goes into a person’s body does not defile that person before God. It is the “evil things” coming out of the heart (in the form of thoughts, words and actions) that defile a person (Mk. 7:23). Jesus urges us to listen carefully to what He says. We cannot let evil things proceed from our heart and think we are pure before God: “For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness” (Mk. 7:21-22). Put away evil. Cleanse your heart through Christ and His gospel (Eph. 4:20-24).
