“My son, pay attention to what I say; turn your ear to my words. Do not let them out of your sight, keep them within your heart; for they are life to those who find them and health to one’s whole body. Above all else, guard your heart, for everything you do flows from it. Keep your mouth free of perversity; keep corrupt talk far from your lips. Let your eyes look straight ahead; fix your gaze directly before you. Give careful thought to the paths for your feet and be steadfast in all your ways. Do not turn to the right or the left; keep your foot from evil.” – Proverbs 4:20-27 NIV

If you let your body guide you at all it will lead you down a path of sin. Never obey the flesh since it’s not trustworthy. Instead trust in God to guide you and utilize his wisdom to keep yourself from sin. Never trust your body. Giving it an inch can have it take a mile. Dominate it and tell it where you need to go based on God’s wisdom. Only then will you find success.
