In Exodus chapter 17, we read how the Israelites were petitioning before Moses for water, so they would not die.
I encourage you to read verses 1-6 of the 17th chapter in Exodus, but here is verse 6, "'I will stand before you on the rock at Mount Sinai. Strike the rock, and water will come gushing out. Then the people will be able to drink.' So Moses struck the rock as he was told, and water gushed out as the elders looked on."
Here we read that God instructed Moses to only strike the Rock once, and God will provide the need (in this case, the need was water).
Now lets look at Numbers 20.
Please read Numbers 20:2-12
Here we read about, yet again, the people of Israel complaining and rebelling against Moses.
Moses goes before the Lord again, and asks what shall he do. This time however, God tells him to SPEAK to the rock.
When Moses goes before the people, he raises his staff, and strikes the rock, instead of speaking to it as the Lord commanded.
As a result of his disobedience, Moses was NOT allowed to enter the promised land (even after his 40 years of effort in the desert).
WHY DO I BRING THIS UP?
Because this was an example of what was to come.
Jesus is the Rock. He was struck once for us (his crucifixion - the ultimate sacrifice), to provide all that we need.
In the desert with Moses, the need was water for survival. And the rock needed only to be struck one time, even when the people needed the water a second time.
The rock needed only to be hit once, after that the rock was to be spoken to. Jesus has been struck for us, and we now only has to speak to Him for our need.
Do not strike Jesus again, by putting Him on the spot and giving Him ultimatums. SPEAK to Jesus, the Rock of Ages, our Cornerstone.
When we speak to our Rock, Gods refreshing presence will flood our spirit and will renew us like the spring rain.
