Any hungry baby, fast growing child, or a hard working man knows how to, and will demand food that fills the emptiness which comes with hunger. If ignored, hunger causes an intense gnawing desire to be satisfied! If we eat food prepared to nourish and sustain our bodies, these bodies will lack nothing. So, eating wholesome food becomes a daily choice of subsistence. Indeed food, daily food, must be supplied and knowing this, the body demands to be filled religiously.
Could shallowness of mind lead us to believe that only the body is to be fed until full? "Know ye not that yea are the temple of God, and that the Spirit of God dwelleth in you" (1 Corinthians 3:16)? A mind is housed within this body and it seeks to be fed also. It should be. It needs food to sustain eternal life! Paul was given grace to preach "the unsearchable riches of God" (Ephesians 3:8). Our soul food. "If so be ye have tasted that the Lord is gracious," why stop with taste? Desire more of the Word, seek and search after the "bread of life which came down from heaven" (John 6:51). Jesus said, "I am that bread of life" (John 6:48).
How often are we to feed our souls, you ask? On a continual basis, never ceasing. The Bible says "Till we all come in the unity of the faith and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fullness of Christ" (Ephesians 4:13). Never are we to stop feeding our souls. Food is abundantly supplied. Seek first the kingdom of God means just that. We are to become full. Feast on the "unsearchable riches of God" and be filled. Paul knew the need of spiritual feed when he prayed for us "to be strengthened . . . rooted and grounded in love, and to comprehend with all saints . . ." and finally "to know the love of Christ, which passeth knowledge, that ye might be filled with all the fullness of God" (Ephesians 3:18-19).
Now, if you have been just tasting and are still hungry, remember God loves you. He has prepared a table and says "Come unto me all ye that are heavy laden, and I will give you rest (Matthew 11:28). Accept the invitation to be filled with soul food! Eat and eat and eat from that table and live! "For this is the love of God, that we keep his commandments: and his commandments are not grievous" (1 John 5:3). "Give praise unto him that is able to do exceedingly abundantly above all that we ask or think according to the power that worketh in us" (Ephesians 3:20). His power is beyond anything we can ever imagine so why not try being filled with the fullness of God?
