But we didn't know Lord!

John 1:6-14
There came a man who was sent from God; his name was John. He came as a witness to testify concerning that light, so that through him all men might believe. He himself was not the light; he came only as a witness to the light.

The true light that gives light to every man was coming into the world.  

He was in the world, and though the world was made through him, the world did not recognize him. He came to that which was his own, but his own did not receive him.

Yet to all who received him, to those who believed in his name, he gave the right to become children of God— children born not of natural descent, nor of human decision or a husband's will, but born of God.

The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.
NIV

John 16:2-11
They will do such things because they have not known the Father or me. I have told you this, so that when the time comes you will remember that I warned you . I did not tell you this at first because I was with you. 

"Now I am going to him who sent me, yet none of you asks me, 'Where are you going?' Because I have said these things, you are filled with grief. 

But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. 

When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment: in regard to sin, because men do not believe in me; 

in regard to righteousness, because I am going to the Father, where you can see me no longer; and in regard to judgment, because the prince of this world now stands condemned. 
NIV

Jer 1:4-19

The word of the LORD came to me, saying,

"Before I formed you in the womb I knew you, before you were born I set you apart;I appointed you as a prophet to the nations."

"Ah, Sovereign LORD," I said, "I do not know how to speak; I am only a child."

But the LORD said to me, "Do not say, 'I am only a child.' You must go to everyone I send you to and say whatever I command you. 8 Do not be afraid of them, for I am with you and will rescue you," declares the LORD.

Then the LORD reached out his hand and touched my mouth and said to me, "Now, I have put my words in your mouth. See, today I appoint you over nations and kingdoms to uproot and tear down, to destroy and overthrow, to build and to plant."

The word of the LORD came to me: "What do you see, Jeremiah?"
"I see the branch of an almond tree," I replied.

The LORD said to me, "You have seen correctly, for I am watching to see that my word is fulfilled."

The word of the LORD came to me again: "What do you see?"
"I see a boiling pot, tilting away from the north," I answered.

The LORD said to me, "From the north disaster will be poured out on all who live in the land.

I am about to summon all the peoples of the northern kingdoms," declares the LORD.
"Their kings will come and set up their thrones in the entrance of the gates of Jerusalem;they will come against all her surrounding walls and against all the towns of Judah.

I will pronounce my judgments on my people because of their wickedness in forsaking me,in burning incense to other gods and in worshiping what their hands have made.

"Get yourself ready! Stand up and say to them whatever I command you. Do not be terrified by them, or I will terrify you before them.

Today I have made you a fortified city, an iron pillar and a bronze wall to stand against the whole land — against the kings of Judah, its officials, its priests and the people of the land.

They will fight against you but will not overcome you, for I am with you and will rescue you," declares the LORD.
NIV

Luke 19:39-44
Some of the Pharisees in the crowd said to Jesus, "Teacher, rebuke your disciples!"

"I tell you," he replied, "if they keep quiet, the stones will cry out ."  

As he approached Jerusalem and saw the city, he wept over it and said, "If you, even you, had only known on this day what would bring you peace — but now it is hidden from your eyes. 

The days will come upon you when your enemies will build an embankment against you and encircle you and hem you in on every side. 

They will dash you to the ground, you and the children within your walls. They will not leave one stone on another, because you did not recognize the time of God's coming to you."  
NIV
