Isaiah 44:3
"For I will pour water upon him that is thirsty, and floods upon the dry ground: I will pour my spirit upon thy seed, and my blessing upon thine offspring:"
Thirsty and Hungry are defined as feeling a need to drink or eat something.
There is nothing like trying to fill the hunger and thirst pains. Hunger pains will drive people to do things they normally would not do. I think of Cain who returned from hunting and smelt his brother's pottage. He was so hungry that he gave up the birthright to fill the hunger pains. The children of Israel were so thirsty in the wilderness that they murmured against God and Moses, and even thought of killing Moses because they were thirsty. The need to fill the appetite for hunger and thirst is great.
Hunger and thirst isn't only a desire for food and water, but it can also be placed on objects or humans. Throughout the Scriptures God shows us that we should be thirsty for His presence. We should hunger for righteousness and His Words. The problem is that because we are sinners, our flesh will also hunger and thirst for things of this world. There is a difference between a hunger and thirst for spiritual and fleshly things. The flesh can never be filled, while the hunger and thirst for God can.
Christian, when you start hungering and thirsting for the things of this world, you will find that they may give temporal satisfaction, but they will leave you hungry and thirsty again. Hebrews 11:25 says, "Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season;" Sin and the flesh will only fill the hunger and thirst pains for a short season, then afterwards you will be hungry again.
I'm reminded of the prodigal son who left his father to live a riotous life. He thought he could prove to his father that the world would fill his appetite, and that he would never need his father again. Sadly, this young man found out that the world and the flesh can only temporarily fill you. He found himself hungry and wanting to eat the slop that the pigs ate. That is exactly how the flesh will leave you.
On the other hand, we have God's promise that He will fill our thirst and hunger if we trust Him. In the verse above God says, "For I will pour water upon him that is thirsty,..." Psalm 81:10 says, "...open thy mouth wide, and I will fill it." Matthew 5:6 says, "Blessed are they which do hunger and thirst after righteousness: for they shall be filled." God is the answer to your hunger and thirst. Instead of running to the world to fill those pains, you should run to God and let Him fill them.
Christian, it doesn't matter what your need is today, God is the only One Who can fill your need. Stop running after the world, and realize that God can fill your need. Run to His Word and you'll find your hunger and thirst will be filled. Run to His life, and you'll find that living the Christian life will satisfy. Seek for righteousness, and you'll find God will fill that hunger and thirst. Your answer is not the world; your answer is God. Don't believe the lies the world has to offer. Only trust God, and you will find the answer for your hunger and thirst is Jesus Christ.
