"That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus." Ephesians 2:7 KJV
"Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ." Ephesians 2:11-13 KJV
"...in time past..."
The LORD God will bless all on-Jews through the nation of His own creation Israel. Israel is created as God’s chosen people, His "elect" for service(holy/sanctify=to be set aside, separated, "severed" for God's use/purpose). God created the nation Israel to have a privileged status before Him as a "peculiar", "different", separated("holy"=sanctified) people:
"But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the LORD doth put a difference between the Egyptians and Israel." Exodus 11:7 KJV

"For from the top of the rocks I see him, and from the hills I behold him: lo, the people shall dwell alone, and shall not be reckoned among the nations." Numbers 23:9 KJV
"For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth." Deuteronomy 7:6 KJV
"Only the LORD had a delight in thy fathers to love them, and he chose their seed after them, even you above all people, as it is this day." Deuteronomy 10:15 KJV
"For thou art an holy people unto the LORD thy God, and the LORD hath chosen thee to be a peculiar people unto himself, above all the nations that are upon the earth." Deuteronomy 14:2 KJV

"And he returned to the man of God, he and all his company, and came, and stood before him: and he said, Behold, now I know that there is no God in all the earth, but in Israel: now therefore, I pray thee, take a blessing of thy servant." 2 Kings 5:15 KJV
"For the LORD hath chosen Jacob unto himself, and Israel for his peculiar treasure." Psalms 135:4 KJV
"He sheweth his word unto Jacob, his statutes and his judgments unto Israel. He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the LORD." Psalms 147:19-20 KJV
"You only have I known of all the families of the earth: therefore I will punish you for all your iniquities." Amos 3:2 KJV
In time past, Gentiles are blessed through Israel's rise to kingdom glory(Isaiah 49:6 KJV, Luke 2:30-32 KJV) as "...the Priests of the LORD....", "...the Ministers of our God:..."(Isaiah 61:6 KJV), "...as His "... messenger..."(Isaiah 42:19 KJV), His "...servant..." He has "chosen..." as His "...elect...(Isaiah 41:8 KJV , Isaiah 44:1 KJV, Isaiah 45:4 KJV, Isaiah 54:17 KJV, Isaiah 65:9 KJV). Israel was to become the LORD God's witness to the unbelieving world of the promised seed , the Lord Jesus Christ(Galatians 3:16 KJV), that there is one true and living God(Isaiah 43:1 KJV, Isaiah 43:10-12 KJV; Matthew 24:14 KJV; Luke 24:48 KJV; Acts 1:8 KJV; Acts 10:41-43 KJV):
" But now thus saith the LORD that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine......Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me. I, even I, am the LORD; and beside me there is no saviour. I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the LORD, that I am God." " Isaiah 43:1 KJV, Isaiah 43:10-12 KJV
And thus, Israel was to be the LORD God's vessel(Jeremiah chapter 18, 19:11 KJV; Isaiah 52:11 KJV) by which "all families of the earth(shall) be blessed"(Genesis 12:2-3 KJV) through the Lord Jesus Christ. Israel was to be the appointed channel and were to be delivered from the curse of the law in order that the blessing of Abraham might come through the Lord Jesus Christ:

"But now..."
After the nation of Israel's(temporary-my emphasis)"stumble, fall, diminishing, casting away, blindness, unbelief"(Romans 11:11-26 KJV), as documented historically in the book of Acts(which is a historical transition period explaining Israel's fall and subsequent removal temporarily as the "channel/"vessel"/"instrument"), the LORD God temporarily set aside the prophetic program, which dealt primarily with Israel alone, and raised up a new apostle, and yes, a new program, the mystery program, the dispensation of the grace of God, that was unforeseen in any of the prophetic books. And now,there is no more "....middle wall of partition..."(Ephesians 2:14 KJV). The LORD God is no longer, for now(there will be in the future, as the LORD God is faithful, although mankind is not, and "makes good" on His promises to the believing remnant of the nation Israel, for His glory..."Israel my glory"-Is. 46:13 KJV), distinguishing/discriminating/putting a "difference" or a "separation", between Jew and Gentile(Romans 10:12 KJV), and God "...hath concluded all under sin..." (Romans 11:32 KJV), and God "...hath concluded all under sin..."(Galatians 3:22 KJV), and is no longer during this "...dispensation of the grace of God..."(Eph. 3:2 KJV) bestowing blessings upon those that bless Israel, that honor Israel,per per Genesis 12:2 KJV, despite many of the "Messianic" ministries proclaiming/asserting that He is.
"For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him." Romans 10:12 KJV
"Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all." Colossians 3:11 KJV
"There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus." Galatians 3:28 KJV
"For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;..." Ephesians 2:14 KJV
"That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel." Ephesians 3:6(see also 1 Cor. 10:17 KJV, 1 Cor. 12:12-13 KJV
And thus, survey Ephesians 2......The setting forth the basic three-fold division in God’s dealing with mankind:
Time past, per verses 11,12): Genesis through Acts(a transition period)
But now, per verse 13: Romans through Philemon
The ages to come,per verse 7: Hebrews through Revelation
Memorize this lay out-details.....The result.... an overview of when, and to whom it was written, and explains the seemingly, yes, "contradictory" passages in the Holy Bible, and removes the "fog" through understanding the divine, definite distinction/difference God made in "time past"(the prophetic program), as opposed to the divine no distinction/difference today in this dispensation's "but now"(the mystery program).
For example:
1. The Lord Jesus Christ's seemingly puzzling statement:
".... for salvation is of the Jews." John 4:22 KJV
Not many would contend that our Lord is proposing that salvation is given through the Jews, in a literal sense. No, the Lord Jesus Christ, as "... a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers:..."(Romans 15:8 KJV-the promises being the covenants/promises given only to Israel), was reaffirming Israel's honored, exalted status as the channel/vessel/vehicle by which the world would be blessed through her instrumentality as a nation of priests, ministers, witnesses....., and as the "blood line" by which the seed should come, i.e., the Lord Jesus Christ.
2. The Lord Jesus Christ's seemingly puzzling actions toward "...a woman of Canaan..." in Matthew chapter 15. He rebuked her, and "... answered her not a word..."(verse 23), and told her, in no uncertain terms, that "..I am not sent but unto the lost sheep of the house of Israel"(verse 24), and referred to her as a "dog"(verse 26-Gentiles were referred to as such by the Jews)="he wouldn't touch a Gentile with a 10 foot pole"! He thus recognized the "difference" between the "chosen" people of Israel and Gentiles, as divinely ordered throughout the OT, and thus "the children's bread"(verse 26) refers back to the Abrahamic covenant provision of Genesis 12:3 KJV ( and confirms Paul's point in Romans 15:8 KJV):
"And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed." Genesis 12:3 KJV
That is-through Israel
And notice that the Lord Jesus Christ only honored her request after she acknowledged and honored Israel's special, privileged status as the vessel, the channel:
"And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters' table. Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour." Matthew 15:27-28 KJV
This "great faith" of which the Lord is pointing out is her faith in the Abrahamic covenant. She acknowledged her position as a "dog", and Israel's exalted status as the channel of blessing(a difference between Jew and Gentile), and thus, because she blessed Israel(" that bless thee"-Gen. 12:3 KJV), and the Lord Jesus Christ blessed her("I will bless them that bless thee"-Gen 12:3 KJV).
3. A similar situation to the preceding is given in Luke chapter 7. Notice the centurion is a Gentile. And why did the Lord Jesus Christ honor his request to heal his servant?:
"For he loveth our nation, and he hath built us a synagogue." Luke 7:5 KJV
The centurion demonstrated his "...great faith..."(7:9) in believing the Abrahamic covenant, and recognizing the "difference":-he "blessed Israel" per Luke 7:5 KJV. And the Lord Jesus Christ blessed him accordingly. And on and on....
