The deep truth in Exodus 16 is that God wants to change our diet. The crucial point here is not whether or not we love the world; it is whether or not our diet has been changed. There is a tremendous difference between learning not to love the world and having a change of diet.
As we seek the Lord for a new beginning and for the supply of manna, we need to turn to our spirit. However, it is easy for us to exercise the mind instead of the spirit. Because this is our tendency, it is a good habit to contact the Lord in the Word before we become occupied with the affairs of the day. Once we have become involved in so many things, it is much more difficult to exercise our spirit to contact the Lord. The first thing we should do each morning is to come to the Lord in the Word and feed on Him.
Just as manna sustained nearly two million people in the wilderness for forty years, so Christ as the real manna sustains the church today. This manna does not have its source on earth; it comes down from heaven where God is. Thus, manna is not only heavenly food, but also godly food. On the one hand, the Lord Jesus is “the bread out of heaven”; on the other hand, He is “the bread of God,” the One who came down out of heaven to be our food (John 6:32-33).
