People need more than bread for their life; they must feed on every word of God. Matthew 4:4
Bread is indispensable to life. We all understand this. However strong a person may be, if he takes no nourishment he will grow weaker and eventually die. Even so with the Word of God.
Bread must be eaten. I may know all about bread. I may give it to others. I may have bread in my house and on my table to great abundance, but that will not help me. I must eat the bread. If through illness I am unable to eat it, I shall die. Likewise, mere knowledge of God’s Word and even preaching it to others will not help me. It is not enough to think about it. I must feed on God’s Word and take it into my heart and life.
Bread must be eaten daily, and the same is true of God’s Word. The psalmist says: “They delight in doing everything the LORD wants; day and night they think about His law” Psalm 1:2). “Oh how I love Your law! I think about it all day long” (Psalm 119:97). To secure a strong and powerful spiritual life, spending time in God’s Word every day is indispensable. When on earth the Lord Jesus learned, loved, and obeyed the word of the Father. If you seek fellowship with Him, you will find Him in His Word.
