One can go 21 days without food, even longer. Some have survived 60 days without food. Going without water is another story. By the time you feel thirsty, you are already starting to dehydrate.
Signs of dehydration in adults:
Muscle fatigue,• Reduced cognitive processing• Dizziness• Confused or dazed states of awareness• Thirst• Infrequent urination and dark-colored urine• Dry mouth
If conditions are good you can go three, perhaps four days without water. After that your organs start to shut down, followed by death. However, in a desert, I don’t believe one would last long.
Israel is wandering in the desert; they have no water; over a million people — good luck. The Israelites are complaining to Moses. So, he talks to God and gets direction.
“……Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go. Behold, I will stand before thee there upon the rock in Horeb; (Horeb is Sinai, where Moses gets the Ten Commandments) and thou shalt smite the rock, and there shall come water out of it, that the people may drink…” (Exodus 17:5-6)
So, the same rod he used to strike the river to turn to blood, he now uses to strike the rock in Horeb to bring forth water –amazing! This rod that brought mercy to the Israelites, wreaked judgment upon the Egyptians.
Now, many years have passed. From all the conflicting timelines and notes I’ve read, it seems to be 35 to possibly 40 years later and they are murmuring for water once again.
“Take the rod, and gather thou the assembly together, thou, and Aaron thy brother, and speak ye unto the rock before their eyes; and it shall give forth his water, and thou shalt bring forth to them water out of the rock: so thou shalt give the congregation and their beasts drink….” “And Moses lifted up his hand, and with his rod he smote the rock twice.” (Numbers 20:8,11)
“And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.” (I Corinthians 10:4)
This Rock was to only be struck once because: “So Christ was once offered to bear the sins of many, and unto them that look for him shall he appear the second time without sin unto salvation.” (Hebrews 9:28)
Jesus is on the cross and has already died. “But one of the soldiers with a spear pierced his side, and forthwith came there out blood and water.” (John 19:34)
“…If anyone is thirsty, let him come to Me and drink. He who believes in Me, as the Scripture said, ‘From his innermost being will flow rivers of living water. But this He spoke of the Spirit, whom those who believed in Him were to receive…” (John 7:38-39 NASB)
If we wait to drink until we are thirsty, we are already starting to dehydrate. Makes me wonder, what if I’m not thirsting for God’s spirit?
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: IS 44:3
Let us speak to The Rock, “Oh Lord, let me constantly drink from your living water.”
