بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ
In the Name of Allah, the Most Beneficient, the Most Merciful
Allah Glorified and Exalted is He says in the Holy Quran:
And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and confirmation of the Law that had come before him: a guidance and an admonition to those who fear Allah
(Al Maidah 5:46)
Islam teaches about Jesus, the Promised Messiah (peace be upon him), that he was sent to confirm the Law which was revealed before him, and that the nature of his revelation, the Gospel, was only to confirm and strengthen that Law which before Allah had revealed to Moses (peace be upon him). The laws and regulations which Allah reveals is not a burden or something that should be resented, rather it is a real blessing as it gives mankind guidance to lead their lives in a good way and become righteous. Righteousness means to obey Allah, so how can one be righteous if there is nothing to obey? But with regard to Christianity, its true founder (Paul of Tarsus) taught the Law of God is a curse, and that Jesus abolished this Law because it was a curse:
"Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: 'Cursed is everyone who is hung on a tree.'" (Galatians 3:13)
Leaving aside Paul's absurdity that one curse can substitute or relieve another, the point here is that he considered the Law a curse. He considered heavenly guidance to be too great a burden for man to endure (especially his potential gentile converts). So he began to proclaim that Jesus had come to totally abolish the Law:
"by abolishing in his flesh the law with its commandments and regulations. His purpose was to create in himself one new man out of the two, thus making peace" (Ephesians 2:15)
Now the true colors and motivation of Paul's deviant theology is revealed. The reason he propogated that Jesus abolished the Law with its commandments and regulations was so the gentiles, who were adverse to the strict Mosaic law and were more inclined to paganistic idolatrous hedonism, could also join the church which Jesus established without having to make any significant sacrifice. Paul was no doubt a satanic agent sent by Hell to twist Jesus's teaching by adding pagan doctrines and concepts and thereby creating a new religion separate and cut off from its Israelite roots. Jesus in fact warned against such "wolves in sheep's clothing":
"Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves." (Matthew 7:15)
From the words of Jesus himself, it is clear he never intended to do away with the Law of Moses, and I will quote to your several proofs for this:
"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them." (Matthew 5:17)
This saying of Jesus completely repudiates Paul's contention that Jesus came to abolish the law with its commandments and regulations. Jesus didn't come to abolish, but to fulfill, to uphold it, to fulfill the prophecies that point to him (which is why he mentioned the Prophets as well as the Law in this particular verse). Some Christian apologists will say that by fulfilling the Law, Jesus completed it or finished it. However, if we examine this verse in context we see that this was definitely not Jesus's intention:
"I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven." (Matthew 5:18-20)
Jesus has so emphasized following the Law for his followers that he even warned them that in this regard they must even surpass the righteousness of the strict observant Pharisees and teachers of the Law otherwise they will be denied entrance into the kingdom of Heaven. This whole concept is the exact opposite of Paul's idea that works and deeds are not the standard of salvation. In fact, Jesus made clear that even believing in him is not enough to guarantee salvation:
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven." (Matthew 7:21)
So it is doing the Father's will, it is obeying His laws and commandments which will make one enter the kingdom of heaven, rather than simply believing in Jesus as mainstream Christians zealously believe.
Jesus even went further to state that although the Pharisees and teachers of the Law are hypocrites because they do not practice what they preach, nonetheless Jesus's followers must follow exactly what they teach. And what do the teachers of the Law teach if not the Law?
"The teachers of the law and the Pharisees sit in Moses' seat. So you must obey them and do everything they tell you." (Matthew 23:2-3)
Part of the reason Allah revealed the Holy Quran and sent the Seal of Prophets, Muhammad (peace and blessings upon him) was to restore the original message of Jesus and to refute the Pauline and trinitarian deviations. The Holy Quran explains that Jesus (peace be upon him) was the Messiah, and the Messiah was meant to be sent for the Children of Israel only:
And remember, Jesus, the son of Mary, said: "O Children of Israel! I am the apostle of Allah (sent) to you, confirming the Law (which came) before me
(As Saff 61:6)
"I was sent only to the lost sheep of Israel." (Matthew 15:24)
And when Jesus was sending out his twelve disciples to preach his Gospel, he gave them strict instructions not to venture into the towns of the gentiles and samaritans:
"These twelve Jesus sent out with the following instructions: 'Do not go among the Gentiles or enter any town of the Samaritans. Go rather to the lost sheep of Israel.'" (Matthew 10:5-6)
All this clearly shows Jesus (peace be upon him) was a Messenger of God but was sent only for the Israelites, and unlike what Paul taught, not for the gentiles or goyim as well...
