John 18: 36-37
36 Jesus answered, "My kingdom is not of this world.  If My kingdom were of this world, then My servants would be fighting so that I would not be handed over to the Jews; but as it is, My kingdom is not of this realm." 
37 Therefore Pilate said to Him, "So You are a king?" Jesus answered, "You say correctly that I am a king For this I have been born, and for this I have come into the world, to testify to the truth Everyone who is of the truth hears My voice." 

The birth, death and resurrection of Jesus it the focal point of all history!  All the old testament looks forward to it and all Christians look back at it.  Jesus came to establish a Kingdom.  The Jews handed Jesus over because they thought it was suppose to be an earthly kingdom and He did not deliver the way the Jewish leadership wanted.  They did not understand that the Kingdom of God prophesied in the old testament is not of this realm.  They wanted the Romans kicked out and the nation re-established as in the days of David and Solomon.

Remember what John the Baptist preached. 
Matthew 3:2
“Repent, for the kingdom of heaven is at hand.”

Jesus preached. 
Matthew 4:17
From that time Jesus began to preach and say, "Repent, for the kingdom of heaven is at hand." 

When Jesus sent out the twelve to the Nation of Israel, He told them... 
Matthew 10:5-7
5 These twelve Jesus sent out after instructing them: "Do not go in the way of the Gentiles, and do not enter any city of the Samaritans; 
6 but rather go to the lost sheep of the house of Israel. 
7 "And as you go, preach, saying, 'The kingdom of heaven is at hand.' 

In Matthew 15:7-28 we see Jesus call the Pharisees hypocrites and He moves the ministry out from Israel and opens it the outside world;
Matthew 15:21-28
21 Jesus went away from there, and withdrew into the district of Tyre and Sidon. 
22 And a Canaanite woman from that region came out and began to cry out, saying, "Have mercy on me, Lord, Son of David; my daughter is cruelly demon-possessed." 
23 But He did not answer her a word. And His disciples came and implored Him, saying, "Send her away, because she keeps shouting at us." 
24 But He answered and said, "I was sent only to the lost sheep of the house of Israel." 
25 But she came and began to bow down before Him, saying, "Lord, help me!" 
26 And He answered and said, "It is not good to take the children's bread and throw it to the dogs." 
27 But she said, "Yes, Lord; but even the dogs feed on the crumbs which fall from their masters' table." 
28 Then Jesus said to her, "O woman, your faith is great; it shall be done for you as you wish." And her daughter was healed at once. 

Why did she call Jesus the Son of David?  Why not call Him the Son of Abraham, Isaac or Jacob?  Because the kingdom was promised to David which I will show you in a few verses. 

Notice that Jesus is in Tyre and Sidon.  This area was Gentile territory and not part of Israel.  This story shows that the nation of Israel has been rejected and this marks the transition of Jesus' ministry to the outside world.  As a Gentile, this is a very important part of Jesus' life that applies directly to me.  The salvation of the Living God has been rejected by Israel and now is offered to the entire world. 

Soon after these events Jesus sent out the seventy to the world. 
Luke 10:1
Now after this the Lord appointed seventy others, and sent them in pairs ahead of Him to every city and place where He Himself was going to come. 

Luke 10:8-9
8 Whatever city you enter and they receive you, eat what is set before you; 
9 and heal those in it who are sick, and say to them, 'The kingdom of God has come near to you.'

In 1 Chronicles 17: 1-14 we see the story of David wanting to build a proper covering for the ark of the covenant.  In the last sentence of verse ten, God tells David He will build a house for him.  Look at the last sentence in verse 14. 

1 Chronicles 17: 9-14
9 I will appoint a place for My people Israel, and will plant them, so that they may dwell in their own place and not be moved again; and the wicked will not waste them anymore as formerly, 
10 even from the day that I commanded judges to be over My people Israel. And I will subdue all your enemies. 
Moreover, I tell you that the Lord will build a house for you. 
11 "When your days are fulfilled that you must go to be with your fathers, that I will set up one of your descendants after you, who will be of your sons; and I will establish his kingdom. 
12 "He shall build for Me a house, and I will establish his throne forever. 
13 "I will be his father and he shall be My son; and I will not take My lovingkindness away from him, as I took it from him who was before you. 
14 "But I will settle him in My house and in My kingdom forever,and his throne shall be established forever."'" 

David misunderstood and initially thought God was talking about Solomon, but in his last words David understands God's plans.  Take a look at verse five of 2 Samuel 23:1-5. 
2 Samuel 23:5
Truly is not my house so with God?  For He has made an everlasting covenant with me, Ordered in all things, and secured; For all my salvation and all my desire, Will He not indeed make it grow? 

David wrote the following Psalm about the covenant God made with him. 
Psalm 89:34-37
34 "My covenant I will not violate, Nor will I alter the utterance of My lips. 
35 "Once I have sworn by My holiness; I will not lie to David. 
36 "His descendants shall endure forever And his throne as the sun before Me. 
37 "It shall be established forever like the moon, And the witness in the sky is faithful." Selah. 

You see from above that the kingdom was promised to David, the Messiah was promised to Abraham (Genesis 22:18; "In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.") and the Prophet was promised to Moses (Deuteronomy 18:15; The LORD your God will raise up for you a prophet like me from among you, from your countrymen, you shall listen to him.). 

Abraham, Moses and David are sure the heavy weights in the old testament, but God also spoke about His kingdom and His Messiah using other prophets.  Look at the following passages from Daniel and Isaiah.

Daniel 2:44-45
44 "In the days of those kings the God of heaven will set up a kingdom which will never be destroyed, and that kingdom will not be left for another people; it will crush and put an end to all these kingdoms, but it will itself endure forever. 
45 "Inasmuch as you saw that a stone was cut out of the mountain without hands and that it crushed the iron, the bronze, the clay, the silver and the gold, the great God has made known to the king what will take place in the future; so the dream is true and its interpretation is trustworthy." 

This was when Daniel told King Nebuchadnezzar the dream he had and the interpretation.  God was telling mankind when the Messiah was going to come to the earth.  It was during the reign of the forth kingdom in the dream.  The stone cut from the mountain without hands is Jesus.  Jesus is the Rock of our salvation.

Daniel 7:27
Then the sovereignty, the dominion and the greatness of all the kingdoms under the whole heaven will be given to the people of the saints of the Highest One; His kingdom will be an everlasting kingdom, and all the dominions will serve and obey Him.'

Isaiah 25:6-12
6 The Lord of hosts will prepare a lavish banquet for all peoples on this mountain; A banquet of aged wine, choice pieces with marrow, And refined, aged wine.
7 And on this mountain He will swallow up the covering which is over all peoples, Even the veil which is stretched over all nations.
8 He will swallow up death for all time, And the Lord GOD will wipe tears away from all faces, And He will remove the reproach of His people from all the earth; For the LORD has spoken. 
9 And it will be said in that day, "Behold, this is our God for whom we have waited that He might save us. This is the LORD for whom we have waited; Let us rejoice and be glad in His salvation." 
10 For the hand of the Lord will rest on this mountain, And Moab will be trodden down in his place As straw is trodden down in the water of a manure pile.
11 And he will spread out his hands in the middle of it As a swimmer spreads out his hands to swim, But the Lord will lay low his pride together with the trickery of his hands.
12 The unassailable fortifications of your walls He will bring down, Lay low and cast to the ground, even to the dust.

When Adam disobeyed God, death entered our world.  Jesus defeated death for us.
Acts 2:24
"But God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power. 

Isaiah 55:1-5
1 "Ho! Every one who thirsts, come to the waters; And you who have no money come, buy and eat.  Come, buy wine and milk Without money and without cost.
2 "Why do you spend money for what is not bread, And your wages for what does not satisfy?  Listen carefully to Me, and eat what is good, And delight yourself in abundance.
3 Incline your ear and come to Me.  Listen, that you may live; And I will make an everlasting covenant with you, According to the faithful mercies shown to David. 
4 "Behold, I have made him a witness to the peoples, A leader and commander for the peoples.
5 "Behold, you will call a nation you do not know, And a nation which knows you not will run to you, Because of the Lord your God, even the Holy One of Israel; For He has glorified you."
