If we’re not feeding ourselves spiritually we will hunger and thirst spiritually, no matter how satisfied we are physically.
Blessed are they which do hunger and thirst after righteousness: for they shall be filled.–Matthew 5:6
The foundational requirement for all godly living is to hunger and thirst after righteousness. This type of hunger is seen in Moses, the psalmist and the apostle Paul. The spiritual condition of Christians throughout their lives will depend on their hunger and thirst for the presence of God, the Word of God, communion of Christ, the fellowship of the Spirit, righteousness, and the return of the Lord.
The Christian’s hunger for the things of God is destroyed by worldly anxiety, deceitfulness of wealth, desire for things and life’s pleasures and failure to abide in Christ. When the hunger of believers for God and His righteousness is destroyed, they will die spiritually. For this reason it is essential that we be sensitive to the Holy Spirit’s convicting work in our lives.
Isaiah 55:1, “Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come ye, buy, and eat; yea, come, buy wine and milk without money and without price.” A big prerequisite for salvation is spiritual hunger and thirst for forgiveness and for the right relationship with God. We must repent of our sins and draw near to Him in faith; and hunger and thirst for God’s righteousness and the power of His kingdom continue to be vital conditions for receiving the fullness of His Spirit.
Then in Isaiah 65:13, “Therefore thus saith the Lord God, Behold, my servants shall eat, but ye shall be hungry: behold, my servants shall drink, but ye shall be thirsty: behold, my servants shall rejoice, but ye shall be ashamed.” We can physically be full, and physically not be thirsty, but if we don’t have our relationship with God right and receiving our spiritual nutrition then we’re going to be spiritually hungry.
When we get so hungry that we will eat anything in the house, even that food that we bought some time ago and we always pass up because it doesn’t sound good; that’s the hunger we need for God. That thirst that we have when your mouth starts getting so dry and you would be thankful for a couple of drops of water just to wet your mouth; that’s the thirst we should have for God. Not sometimes, but all the time. We should be striving to know Him more by His Word and by having a relationship with Him. Reading the Bible will only satisfy the hunger a little bit. To fully have our hunger satisfied we need Him and only Him.
