Proverbs 4:20-22, 20 My son, give attention to my words; Incline your ear to my sayings. 21 Do not let them depart from your eyes; Keep them in the midst of your heart; 22 For they are life to those who find them [this process was more than just reading the Bible. It was reading the Bible in such a way as to find out how to receive what God was offering.], And health [medicine] to all their flesh. (NKJV)
God is promising us something that would be medicine that would bring health to all our flesh. He also gave us the directions to this medicine, just as a doctor would on a medicine bottle. There are four specific instructions for taking God's Word as medicine for the physical body 1) Attend to my Words, 2)Incline your ear to My sayings, 3)Do not let them depart from your eyes, 4) Keep them in the midst of your heart.
