Context is always critical in serious Bible Study. This is because a belief held without a context is simply a pretext or an alleged reasoning or notion, then not based upon a substantiated Biblical fact.

We need to approach our consideration of Jesus of Nazareth's ministry according to its Biblical context. So first we need to establish the context of Jesus' ministry by noting that Jesus came to His own... the nation Israel, called "the circumcision" (cf., Rom 15:8). He came as Israel's long promised Messiah, savior and King.

Some of the most beautiful messianic promises written during the period of the united northern and southern kingdoms of Israel are found in the Psalms. Some come from the pen of Israel's King David (e.g. Psalm 22, 110); while Psalm 72 was the work of Israel's King Solomon. God spoke through the psalmists of Israel, foretelling the arrival of Messiah, the Israel's coming King.

• Psalm 2 speaks of the Messiah as the One whom God will install as His King over Israel (v 7). Messiah will be given the nations as His inheritance, and He will rule over those who seek to oppose Him (vss. 1-3, 8-9). The nations are thus urged to worship God now, or face the wrath of the coming King.
• Psalm 22 portrays the suffering of Messiah of Israel on the cross of Calvary. It begins with the words which our Lord quoted upon the cross, "My God, my God, why has Thou forsaken me?" thus identifying the Savior with the One whose sufferings are described in this Psalm.
• Psalm 45 is written for the celebration of the king's marriage. It therefore focuses on the splendor and majesty of the coming King of Israel (v 3-6), and upon the fact that His throne is eternal (v 6). The bride of the King loves righteousness and hates wickedness and has been chosen by Him as His bride. The splendor of the bride is described as she has been prepared for her presentation to the King.
• Psalm 72 depicts the reign of the Righteous King of Israel, who judges the people with righteousness and justice, and who vindicates the afflicted. He is the One who will answer the cries of the afflicted and will bring them deliverance.
• Psalm 110 speaks of the installation of the Messiah of Israel at the right hand of God, who will rule over His enemies. Not only is He to rule as King, but He is also an eternal priest after the order of Melchizedek (v 4). He will come to the earth to destroy His enemies, and then reign through a believing Israel as His co-regents on earth for eternity (cf., Rev 5:20, 20:6).
• Psalm 145 speaks of Jesus coming as Israel's eternal King. "Thy kingdom is an everlasting kingdom, and thy dominion endureth throughout all generations." (v13).

Now let's consider some of Jesus of Nazareth's encounters occurring during His earthly ministry.

In encountering the Gentile "Syro-Phoenician woman" seeking deliverance for her daughter (cf., Mark 7:25-30), Jesus of Nazareth told His disciples that He had "come but unto (only to) the lost sheep of the house of Israel" (Matt 15:24), not to the Gentiles (cf., Matt 10:5-6). Gentiles were then referred to as "dogs."

Being "full of grace" (John 1:14), Jesus of Nazareth came as Savior and brought to Israel a foretaste of the blessings of the "kingdom of heaven" that is to come in accord with the Abrahamic Covenant of Gen. 12:1-3 and Davidic Covenant of  2Sam. 7:10-13. Seven times in the four gospels Jesus said "the kingdom of (to come from) heaven is at hand." In fact, after Jesus' resurrection and appearing to His disciples for forty days afterward, we are told He spoke to them "the things pertaining to the kingdom of God" (Acts 1:3, 6).

The promised "everlasting kingdom" will first appear in the Millennium, fulfilling the promised restoration of the Davidic Kingdom in its fullness. Christ will come again a second time, but this time not as a "Lamb of God," but rather "in wrath" to save the believers of Israel from her enemies. Christ will return as "the Son of David," being also the "greater than David" (cf., Matthew 9:27, 22:41-46). He will occupy David's literal physical throne on the literal physical earth. He will set up the literal "kingdom of heaven" on the literal physical earth in the literal physical Jerusalem at the close of the horrific 7-year Tribulation period, which is also called "the seventieth week of Daniel" that precedes His 1,000 year kingdom reign on earth.

Jesus of Nazareth came the first time to "His own (Israel) and they received Him not (John 1:11," He preached... "the kingdom" and spoke of it to "the circumcision (Israel)" (Rom 15:8) 127 times in the four Gospels. Yet, they rejected the king and His kingdom by crucifying Jesus. But after Jesus' death and resurrection He returned again for a short time.

"(He then) shewed himself alive after his passion (cross) by many infallible proofs, being seen of them (His Jewish Disciples) forty days, and speaking of the things Pertaining To THE KINGDOM OF GOD:" (Act 1:3).

The coming of the "kingdom of heaven" to earth, was referred to as "the gospel of the kingdom" in Matt 4:23; it was the focus of the ministry of earthly Jesus of Nazareth to "the circumcision"(Rom 15:8).

Israel historically had long resisted the Lord and His Law; first by killing His prophets as seen in the OT, and by then killing Jesus Himself. Since Israel had long rejected God and his prophets. Jesus' proclamation was that the people of Israel had to, as a Nation, receive John the Baptist's message of the "baptism of repentance."

"he (John the Baptist) came into all the country about Jordan, preaching the Baptism of Repentance for the remission of sins; (Luke 3:3). John said, "... he (Jesus) shall baptize you with the Holy Ghost. (Mark 1:8).

The promise was that repentant Israelites would be baptized in water and "clothed" with the power with the Holy Spirit. God intended that, through Israel, the whole world would then be blessed; the offer of salvation would come through a Holy Spirit anointed Israel as His agents on earth (cf., Rev 5:10, 20:6).

Jesus came as a minister to "the circumcision (Israel)" (Rom 15:8). He performed many miraculous "signs" that were intended to add veracity to His words proclaiming "the kingdom of (from) heaven is at hand." Then after Jesus' ascension to heaven, Peter, at Pentecost, made the bonafide offer of the kingdom... if the nation, under the leaders of Israel, would "repent be baptized for the remission of sins" (Act 2:38, 41)

Peter plainly addressed Israel at Pentecost, specifically as; "ye men of Israel" (Act 2:22, 3:12), saying;

"Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the Presence Of The Lord; 20HE SHALL SEND JESUS CHRIST (the promised Messiah), which before was preached unto you: (Acts 3:19-20).

We know of course that Israel rejected their Messiah; Jesus of Nazareth became a "stumbling stone" (Rom 9:32-33, 11:11-12) to them. Later Israel actually "fell" from their lofty position elevated "above all people" in God's eyes (Exo 19:5), who were "not to be counted as among the nations (Gk., ethnos, Gentiles)" (Num 23:9).

Israel largely rejected the Apostle Peter's words and ultimately did "fall" by unforgivably rejecting the witness of the Holy Spirit when they stoned Stephen to death in Acts 7.

"I  say then, Have they (Israel) stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy. 12 Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness? (Rom 11:11-12)

By these acts Israel has "fallen" and has become "blinded (and set-aside) until the times of the Gentiles is fulfilled" (Rom 11:25, cf. Luke 21:24). Then the age had turned from Israel to the Gentile "body of Christ."

Today Israel is set-aside and will remain so "until" after the completion and rapture (1Thes 4:13-18) of the predominantly Gentile "church, which is the body of Christ" (Eph 1:22b-23a), whose members will dwell "eternal in the heavens" (2Cor 5:1b).

"I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, UNTIL the fulness of the Gentiles be come in. (Rom 11:25)

Thus, Israel's promised "kingdom" on earth has been delayed "UNTIL the times of the Gentiles is fulfilled." Israel's rejection of Christ fulfilled Jesus' words by parable that predicted Israel to say; "we will not have this man to rule over us" (Luke 19:14). So after the cross Israel rejected their 2nd chance that was offered by the witness of Holy Spirit through Stephen, when they stoned Stephen to death (Acts 7:51-60). This rejection of the Holy Spirit was unforgivable. So now, "the kingdom" to come on earth will not come until Christ's 2nd coming at the close of the Tribulation, to establish the Millennial Kingdom reign.
