Why is there a need for Jesus if you are a devout Jew without sin?

Pastor Chris,

Assuming one is a devout Jew—like Jesus, and is faithful to all Mitzvot in the Torah—i.e. the Five Books of Moses, thus is without sin. Contained in the Christians’ “Greek Old Testament,”
Why is there a need for the New Testament—expounding belief in a Messiah, who has yet to appear to protect us? Per Numbers 24;17 & Deuteronomy 18;18.



Jesus is the only person without sin. This is because Jesus does not have a human father. Jesus is the only person in all of eternity who is fully God and fully man (John 1:1-2; 14; Philippians 2:5-11; Colossians 1:15-18). Our sin nature is passed down to us from Adam through our fathers. Thus, we are sinners by nature and we sin by choice. “All have sinned and fall short of the glory of God” (Romans 3:23).

In John 8:46 Jesus asked His opponents, “Can any of you prove me guilty of sin?” Those who were against Him would certainly have pointed out sin in Jesus’ life if they could. They watched Jesus closely, looking for ways to discredit Him. They could not do it.

Being faithful to the Torah does not mean a person can say that they are sin free. A person who is faithful to the Torah must offer sacrifices for sin. The problem is that the sacrifices required in the Torah cannot take away sin. Hebrews 10:11 says, “Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins.”

The sacrifices required in the Torah prepared the way for the ultimate sacrifice that God’s Son would make when He died on the cross. Think of the Old Testament sacrificial system as a preview of what was to come.

When Jesus hung on the cross, God the Father accepted His sacrifice on our behalf as full payment for our sin. Jesus cried out from the cross, “It is finished!” (John 19:30); which means “it is paid in full.” Therefore, when we repent of our sins and place our trust in Jesus as our Redeemer we are forgiven and we gain eternal life (John 3:16-17; 5:24).

It has been said that the New Testament is the Old Testament revealed. In other words, the New Testament explains the Old Testament by telling us about Jesus the Messiah who fulfilled everything the Old Testament was pointing toward. Jesus said it this way, “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).

Should Christians read the Qur'an?

Pastor Chris,
I found out that a Christian friend was reading the Qur’an and I was dismayed that a Christian would read teachings such as this. I encouraged this person to stick to God and read the Bible rather than read teachings such as this. Should Christians be reading these false teachings to better know what these other religions are about and maybe to better witness to these folks? Thank you,

Thank you for your question! The Bible speaks to this issue in many places where it warns us against following false religions and the doctrines of demons. 1 Timothy 4:1-2, “The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons. 2 Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron.” Our enemy, the devil, is always busy. Prowling around like a roaring lion, he is always seeking those whom he might devour (1 Peter 5:8). Deceit is one of the primary ways the devil devours his victims. The devil’s tactic with Adam and Eve was deceit. He deceived them by tempting them to doubt God’s word, thereby influencing them to doubt God Himself.

The Bible says in 2 John 7-11, “Many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist. 8 Watch out that you do not lose what you have worked for, but that you may be rewarded fully. 9 Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son. 10 If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him. 11 Anyone who welcomes him shares in his wicked work.”

A case in point is the nation of Israel itself. Throughout its existence, Israel was warned by God not to involve themselves in the religions and false deities of the nations nearby. They did so and became infected with false worship and false teachings. These actions broke the first two of the Ten Commandments (Exodus 20:1-6). God judged them by sending them away into captivity when Assyria defeated the Northern Kingdom of Israel in 722 B.C. and then Babylon defeated the Southern Kingdom of Judah in 586-587 B.C.

It is interesting to note how the FBI catches counterfeiters. The FBI has the agents in the counterfeit department study genuine currency. By thoroughly studying genuine currency, they are readily able to spot the false currency. If a person masters the truth that is found in the Bible, he will be able to refute whatever heresy the devil throws at him.

It is not necessarily wrong for someone to learn something about another religion for the purpose of looking for ways to witness to them about the truth of Jesus Christ. Extreme caution must be advised, however, because when you are encountering the devil’s lies there is always the danger of being deceived yourself.
