Continuing where I left off:
First set:
2. Looking at modern Orthodox Judaism as a whole, I would have to disagree. Some of their teachings are based on the Old Testament, but they do things differently than they did 2000 years ago and as I already showed, rejecting Jesus consequently means rejecting Moses who wrote about Him. So while it is partially based on revelation from God, on the whole it is not based on revelation from God since it rejects the core of the revelation.
3. The problem is, no one is justified by the Law because no one (other than Jesus of course) was able to perfectly keep it. The Old Covenant can be reckoned to be abolish for those who are in Christ who fulfilled the Law.
Now we know that whatever the (1) Law says, it speaks to (2) those who are under the Law, so that every mouth may be closed and (3) all the world may become accountable to God;
20 because (4) by the works of the Law no flesh will be justified in His sight; for (5) through the Law comes the knowledge of sin. - Romans 3:19-20 NASB
Now that [Gal 2:16] no one is justified by the Law before God is evident; for, "[Hab 2:4; Rom 1:17; Heb 10:38] THE RIGHTEOUS MAN SHALL LIVE BY FAITH." - Galatians 3:11 NASB
For the Law, since it has only (1) a shadow of (2) the good things to come and not the very form of things, [1] can (3) never, by the same sacrifices which they offer continually year by year, (4) make perfect those who draw near.
2 Otherwise, would they not have ceased to be offered, because the worshipers, having once been cleansed, would no longer have had (5) consciousness of sins?
3 But (6) in those sacrifices there is a reminder of sins year by year.
4 For it is (7) impossible for the (8) blood of bulls and goats to take away sins.
5 Therefore, (9) when He comes into the world, He says,
"(10) SACRIFICE AND OFFERING YOU HAVE NOT DESIRED,
BUT (11) A BODY YOU HAVE PREPARED FOR ME;
6
(12) IN WHOLE BURNT OFFERINGS AND sacrifices FOR SIN YOU HAVE TAKEN NO PLEASURE.
7
"(13) THEN I SAID, 'BEHOLD, I HAVE COME
(IN (14) THE SCROLL OF THE BOOK IT IS WRITTEN OF ME)
TO DO YOUR WILL, O GOD.'"
8 After saying above, "(15) SACRIFICES AND OFFERINGS AND (16) WHOLE BURNT OFFERINGS AND sacrifices (17) FOR SIN YOU HAVE NOT DESIRED, NOR HAVE YOU TAKEN PLEASURE in them" (which are offered according to the Law),
9 then He said, "(18) BEHOLD, I HAVE COME TO DO YOUR WILL." He takes away the first in order to establish the second.
10 By this will we have been (19) sanctified through (20) the offering of (21) the body of Jesus Christ (22) once for all. - Hebrews 10:1-10 NASB
3a. The Jews "who sincerely are still following God awaiting the Messiah", are sincerely wrong, which is why they need Christ.
3b. I said previously that the Old Covenant is to be reckoned as abolished to those who are in Christ who fulfilled the Law (ie. we are not bound by the Law of the letter because Christ fulfilled it for us, but the Law didn't go "poof" and disappear, those who reject Christ are expected to keep the entire Law). If a person could keep the Law perfectly, they would be righteous in God's eyes, problem is, we have a sinful nature and thus cannot keep God's Law perfectly and that is precisely why Christ died for our sins.
Second set:
1. We're all in the same boat, we all need Christ.
But now apart from the Law (30) the righteousness of God has been manifested, being (31) witnessed by the Law and the Prophets,
22 even the (32) righteousness of God through (33) faith (34) in Jesus Christ for (35) all those who believe; for (36) there is no distinction;
23 for all (37) have sinned and fall short of the glory of God,
24 being justified as a gift (38) by His grace through (39) the redemption which is in Christ Jesus;
25 whom God displayed publicly as (40) a propitiation (41) in His blood through faith. This was to demonstrate His righteousness, because in the (42) forbearance of God He (43) passed over the sins previously committed;
26 for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier of the one who has faith in Jesus. - Romans 3:21-26 NASB
That's not to say you can't use different tactics when evangelizing to different groups of people, it just means that all need Christ equally. They just as much sinners as everybody else and so they are just as much in need of Christ and thus should be treated as such.
2. The same message is given to all, but the message can be presented differently.
To the [Rom 14:1; 15:1; 2 Cor 11:29] weak I became weak, that I might win the weak; I have become [1 Cor 10:33] all things to all men, [Rom 11:14] so that I may by all means save some. - 1 Corinthians 9:22 NASB
Many people calling themselves Jews know nothing about the Bible, one "Jew" tried to avoid being evangelized by claiming to be Jewish but did not even know who Abraham is. In such a case, you have to start from scratch but when trying to evangelize Biblically literate Jews, using the Old Testament as Abiyah suggested is a great idea. For example:
26 "Moreover, I will give you a (4) new heart and put a new spirit within you; and I will remove the (5) heart of stone from your flesh and give you a heart of flesh.
27 "I will (6) put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances. - Ezekiel 36:26-27 NASB
But He was [3] pierced through for (10) our transgressions,
He was crushed for (11) our iniquities;
The (12) chastening for our well-being fell upon Him,
And by (13) His scourging we are healed. - Isaiah 53:5 NASB
3. The Jews do not believe in the same God as Christians, if you reject the Son, you reject the Father:
nor does anyone know the Father [John 7:29; 10:15; 17:25] except the Son, and anyone to whom the Son wills to reveal Him. - Matthew 11:27 NASB
so that all will honor the Son even as they honor the Father. [Luke 10:16; 1 John 2:23] He who does not honor the Son does not honor the Father who sent Him. - John 5:23 NASB
Paul maintains the need of the Jews for Christ, when evangelizing to the Gentiles he hoped to make the Jews jealous of the salvation which had come to the Gentiles so that some would come to Christ to be saved.
But I am speaking to you who are Gentiles. Inasmuch then as (21) I am an apostle of Gentiles, I magnify my ministry,
14 if somehow I might (22) move to jealousy (23) my fellow countrymen and (24) save some of them. - Romans 11:13-14 NASB
One day all of Israel will turn back to God:
For (38) I do not want you, brethren, to be uninformed of this (39) mystery--so that you will not be (40) wise in your own estimation--that a partial (41) hardening has happened to Israel until the (42) fullness of the Gentiles has come in;
26 and so all Israel will be saved; just as it is written,
"(43) THE DELIVERER WILL COME FROM ZION,
HE WILL REMOVE UNGODLINESS FROM JACOB."
27
"(44) THIS IS MY COVENANT WITH THEM,
(45) WHEN I TAKE AWAY THEIR SINS."
28 From the standpoint of the gospel they are (46) enemies for your sake, but from the standpoint of God's choice they are beloved for (47) the sake of the fathers;
29 for the gifts and the (48) calling of God (49) are irrevocable. - Romans 11:25-29 NASB
Until the fullness of the Gentiles has come in and the Jews turn back to God, they need to be evangelized. The first Christians were Jews so it makes absolutely no sense to withhold the Gospel from them. Also, I am confident that if you asked a Messianic Jew, how he or she feels about this issue, he or she would tell you to preach the Gospel to both Jew and Gentile, and that he or she is very glad that somebody shared the Gospel with him or her.
Hopefully I've been some help to you and haven't taken up too much space
