Ola,
 
I think you have made some very important points regarding Moses as one of the witnesses.
 
I believe that there is much more going on with Moses than most Christians even teachers realize and the incident of his striking the rock the second time is one of the biggest areas of misunderstanding.
 
I have heard many sermons on this but never have I heard one that says what I believe the Holy Spirit revealed to me is really happening. For example, I once heard Chuck Missler say that he believed that God punished Moses over the rock striking incident because Moses misrepresented God to the people, making the people believe that God was angry with them when He was not, and for that God wouldn't let Moses into the promised land.
 
More commonly I have heard many times the teaching that God punished Moses for wrecking the type of the rock being Christ which was only once supposed to be struck for sins and after that all that is needed is to speak to the rock for the saving water to come.
 
But what the Holy Spirit showed me is that Moses is fulfilling a different type. He "describeth" to use the King James word, the righteousness which is of the law that the man which doeth those things shall live by them. In other words (because there is no righteousness from keeping the law) anyone who attempts to be justified by keeping the law is also striking the rock the second time or crucifying to himself the Son of God afresh and when Paul says the man who does that shall live by them he is saying that you won't live at all. It's sarcasm. As if to say good luck with that pal... and he takes the sarcasm to an even greater extreme by suggesting that our attempting to keep the law after Jesus already fulfilled it on our behalf is akin to thinking that we can go up into heaven and help Jesus come down and be born or go down to hell and help Jesus rise from the dead. We cannot contribute to our salvation by being justified by the law. That is Paul's point and any attempt must end in failure even to be raptured.
 
Romans 10:
4.  For Christ is the end of the law for righteousness to every one that believeth.
 5.  For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them.
 6.  But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:)
 7.  Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.)
 8.  But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
 9.  That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
 10.  For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
 
Now, can we see ourselves superimposed with Moses and that we are also in that same position of having to choose between faith in Christ or the law? Righteousness by faith speaks to the rock of Christ and believes on the LORD Jesus and salvation is given. While righteousness of the law is striking the rock the second time and the penalty for this was what happened to Moses.
 
The entire point here is missed if we fail to see our day in sharp focus here. Going in the rapture alive is at stake. If you believe in your heart in the Lord Jesus Christ and trust His promises then you will speak the word of faith to Him and be saved. But if you seek to be justified by keeping any part of the law then you are like Moses striking the rock or crucifying to yourself the Son of God afresh, and you will do as Moses and that generation did and must be rejected by God even though you argue with Him as Moses also did and there will be weeping and gnashing of teeth, you will have to die in this wilderness first before coming into the good land. This is what Moses was describing in his actions. God had us in mind who would be faced with the rapture and Moses did what he did as a testimony.
 
Moses was not punished for wrecking a type of the rock being Christ but we are told that he was doing it to show us what happens to those who will do that same offense. Hebrews said it was for a testimony of those things that would be spoken after. Meaning that many years later God knowing that Apostle Paul would be teaching on the law vs. faith in Christ, God had Moses do this as an object lesson. Yet many Christians fail to even see it. Many teachers have not listened to the Holy Spirit for their lessons and they teach man's or even demon's doctrines and traditions instead. Many teachers say that Moses failed God in this act but God says Moses was faithful and did it for a testimony. Which do you believe?
 
Hebrews 3:
 5.  And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;
 6.  But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
 7.  Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,
 8.  Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:
 
It is clearly pointing to our day and the choice before every one of us is the same as it was then. Faith or the law.
