“there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man…..And He *said to them, “Are you lacking understanding in this way as well? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and goes to the sewer?” (Thus He declared all foods clean.) And He was saying, “That which proceeds out of the man, that is what defiles the man. “For from within, out of the heart of men, proceed the evil thoughts, sexual immoralities, thefts, murders, adulteries, coveting, wickedness, deceit, sensuality, envy, slander, pride, and foolishness. “All these evil things proceed from within and defile the man.”” Mark 7:15, 18-23 LSB https://bible.com/bible/3345/mrk.7.15-23.LSB
It is far easier to judge one another by our outward appearance than to judge each other by our thoughts and words. It is far easier to condemn others for being overweight, drinking too much, or smoking than it is to condemn others for thinking evil or speaking evil. We like to pretend we are good because we don’t do certain things rather than admit to God we are sinners whose hearts are utterly impure and whose thoughts are continually evil against our fellow man. Hate, anger, jealousy, lust, covetousness, unforgiveness, abound in our hearts and minds and these are the things for which we must repent. It only makes sense that if there is a God He would know our innermost being and hold us accountable for being all that He commands, inside and out. The body is the residence of the Holy Spirit for those who are born again so certainly taking care of it matters, but God is not deceived by our physical health that we are spiritually healthy. New bodies await everyone, those who have repented from evil thoughts and words to know the One True God so as to speak His word to others and to live in obedience to everything He has commanded, will receive eternal bodies that always please the Lord. All of us need a Savior, our thoughts and words prove it, let us not deceive ourselves into believing we are good by what we put into our bodies but let us measure ourselves by how much of God’s word and life come out of our bodies.
