BUT I SAY
There is a huge difference between the teachings of Christ and the requirements of the Old Testament. Jesus uses the word “but” to show contrast.
BUT I SAY
Matthew 5:22 But I say unto you that whosoever is angry
Anything Jesus says replaces everything you may have heard. You can either stick with the teachings of Christ or not.
Context
In his first sermon, known as the Sermon on the Mount, Jesus introduces the attitudes and rewards of his kingdom (Matthew 5:1-12). He explains his purpose regarding the law and the prophets, “I am not come to destroy, but to fulfil” (Matthew 5:17-19, Luke 24:44, John 19:30). Just in case one misunderstands the statements of Jesus, he clarifies in the rest of the chapter (Matthew 5:21-48).
Contrast
Note the many times Jesus uses the word “but” to contrast the law, including the Ten Commandments, and his teachings. Kill versus anger (Exodus 20:13, Matthew 5:21-22). Adultery versus lust (Exodus 20:14, Matthew 5:27-28). Divorce without cause versus divorce for fornication (Matthew 5:31-32). Swear versus swear not (Matthew 5:33-34). Vengeance versus non-retaliation (Matthew 5:38-39). Hate versus love (Matthew 5:43-44).
Conclude
Obviously, the passage is establishing the authority of Jesus, the Son of God (Matthew 28:18-20). Moses mentioned that a prophet would come whom the people of God should listen (Deuteronomy 18:15). The bible is very clear on the fulfillment of this prophecy (Acts 3:20-23). Hence, whatever we do must be done by the authority of Jesus (John 2:5, Matthew 17:4-5, Colossians 3:17). Jesus is king in his kingdom (1 Corinthians 15:24-25, Colossians 1:12-13, Hebrews 12:28).
Concern
Instead of standing on the rock of Christ's Words, some are holding to the old law (Matthew 7:24-27). The bible clearly teaches that we are no longer under the law that says, thou shalt not kill, thou shalt not commit adultery, and thou shalt not covet (Matthew 5:21 27 Romans 7:6-7). This is the same law that says Remember the sabbath (Exodus 20:8, Colossians 2:14-17).
