Can Christians explain this to me?

I have thought about this too and I think He doesnt encourage others to proclaim who they believe Him to be- especially the demons who know exactly who He is- because He wants everyone to have a chance to make up their own mind about Him and not be swayed by what others say. This is the only way to truely get into someones heart. We must decide for ourselves from firsthand experience. We must choose to go to be he source on this one. No secondhand reports to cloud or influence our choice to believe Him. What others say about Him will lead either lead us to Him and enable us to discover His truth for ourselves or lead us away from Him in which case we are allowing rumor to decide. (never a good idea)

Of course many did tell about what He did for them and word of Him spread. But He still wants to make sure we get the truth from Him. No coersion. No gossip. There is no substitute for hearing Him speak His truth in your own heart. Once we hear from Him- we are responsible.

In the Gospel of Mark his disciples appear clueless and demons recognize Jesus. When Peter or the others declare him the Messiah he tells them not to talk about it, just as he tells the demons.

You may speculate as to why, but Mark is already acknowledging that Jesus is not messiah in the expected way of the times. He is not the one who will drive out the Romans, reclaim the Temple and bring back the reign of King David. When people act like he is he leaves the scene.

it wasn't His time yet to be revealed

the pace of the gospel of Mark is very quick

Let me use a modern example. There are some "famous" people who are only famous for being famous. They had done nothing worthy or remarkable, just had enough people talking about them. (Remember the sex tapes that launched the "careers" of these ones?)

Jesus wanted people to decide who and what he was based not on stories, but on the facts. As you know from the old "telephone game", each repeating increased the error of the message at the end. (Especially the demons! What possible reason would Christ want the demons to tell everyone that he was the Christ??)

Probably because:

A) the Jews were looking for a 'triumphant' messiah that would set everything right and destroy Rome and set up the Jewish kingdom over all other nations. Christ didn't want everyone to think he was that triumphant vengeful messiah using his power to right all wrongs and set things straight.

In other words, he wanted to reveal himself as the sacrifice on the cross and using his power to reveal himself would have confused the Jews at that time.

B) He needed to be rejected by his people, in order to fulfill the other prophesies about the Messiah being rejected.

C) He wanted people to listen to his TEACHINGS and not his signs/miracles. The Jews had a history of only following God when he was performing miracles for them. Christ wanted a more genuine, internal faith that didn't depend on God revealing his power to them, all the time.

It is kinda the difference between saying "believe the words that are coming out of my mouth" and "only believe me 'cause I prove everything to you"

Christ revealed that he had risen from the death to his disciples in the closed room. The Apostle Thomas didn't believe until he could put his hand in the open wounds of Christ. (he had to see and touch) Christ said "blessed are those who believe but do not see" - showing that faith is better then physical evidence. sometimes.

So I think it all comes down to timing. Human timing - NOT God's. God waits for US to be ready to hear his message, not us waiting on God.

We can not know why the Gospels are different . I think we have to compare: an accident scene where four people saw it but each of them will tell a different thing. It had to be in their own thinking.

“Now the art of the Sophist is, as I believe, of great antiquity; but in ancient times those who practiced it, fearing this odium, veiled and disguised themselves under various names, some under that of poets, as Homer, Hesiod, and Simonides, some, of hierophants and prophets, as Orpheus and Musaeus, and some, as I observe, even under the name of gymnastic-masters, like Iccus of Tarentum, or the more recently celebrated Herodicus, now of Selymbria and formerly of Megara, who is a first-rate Sophist. Your own Agathocles pretended to be a musician, but was really an eminent Sophist; also Pythocleides the Cean; and there were many others; and all of them, as I was saying, adopted these arts as veils or disguises because they were afraid of the odium which they would incur.” (From Plato's "Protagoras")

From Plato’s Theaetetus:

Socrates: “In the name of the Graces, what an almighty wise man Protagoras must have been! He spoke these things in a parable to the common herd, like you and me, but told the truth, his Truth, in secret to his own disciples.”

From Mark 14:10-12

Mark 14:10 When he (Christ) was alone, the Twelve and the others around him asked him about the parables. 11 He told them, "The secret of the kingdom of God has been given to you. But to those on the outside everything is said in parables 12 so that, "'they may be ever seeing but never perceiving, and ever hearing but never understanding; otherwise they might turn and be forgiven!'"

I don't know for sure. My thought is that God wasn't ready for people to know. There is one instance where He tells someone not to say anything, and then the person went and told people anyway and He got mobbed by a crowd of people.

he couldnt let his power to be known due to he would be overwhelmed by demands for help.
