"Man does not live on bread alone, but on every word that comes from the mouth of God."
It is very important that we read & memorize God's word, especially during the good times. Because, if we have His words in our minds & in our hearts. God will bring to mind His truths that we need when we go through any & every trial of this world. That is why, to know the words that come from the mouth of God, we must spend time in His word - reading, studying, praying & memorizing scripture.
Balanced food choices give us the energy & strength to face physical demands. But a balanced relationship with our Savior, is what we need for spiritual strength. And with that, we grow in our spiritual strength, which will help us to grow past our temptations of temporary comforts.
Plus - God wants us to continually be nourished by His word so that we will be able to tell others about His kingdom & righteousness. Share God's love.
