The word of God is our spiritual food; it is most beneficial to our soul, as it's written: "One does not live by bread alone, but by every word that comes forth from the mouth of God." In John 14.23, Jesus said, "Whoever loves me will keep my word, and my Father will love him, and we will come to him and make our dwelling with him." Therefore, surrender yourself to the Lord to become one with him, then you'll be able to keep his word joyfully and effortlessly. To submit to the word of the Lord is to submit to the Lord. This is the most beautiful way of living for God.
