Exodus 23:25 NKJV
So you shall serve the Lord your God, and He will bless your bread and your water. And I will take sickness away from the midst of you.
(Some translations use the word "worship" instead of "serve." You cannot truly worship God and not serve Him.) God promised to bless the food and water of those who served Him. When something is blessed, it will do only good, no harm.
Spiritual parallel: Although the Word is already blessed in general, what is it doing for us individually? When we get into the Word, is it blessing us? Are we being changed from glory to glory. Do we see progress we can measure? We cannot get into the water of the Word haphazardly and expect positive transformation. We must get into the Word as servants of the Lord. When we do, He will bless it and it will do us good. A servant waits on his master. He listens for instructions and carries them out. James explains the right attitude toward God’s Word. (James 1:22-25) He said the doer, not the hearer is blessed.
God told Joshua to approach the Word as a servant – ready to do everything He saw in it. (Joshua 1:8)
Before telling the parable of the house on the rock, versus the house on the sand, Jesus asked a question emphasizing the importance of those calling Him Lord being people of obedience to His commands.
Luke 6:46 NKJV
“But why do you call Me ‘Lord, Lord,’ and not do the things which I say?”
Despite the extreme value of the Word, we need God to bless it to our spirits just like we need His blessing upon our natural food and water for our physical bodies. In both cases, we need to commit to being His servants. We are sons by birth and servants by choice.
