The laws are an everlasting covenant, for a thousand generations, always and forever.
Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant
and mercy with them that love him and keep his commandments to a thousand generations.
Therefore thou shalt love the LORD thy God, and keep his charge, and his statutes,
and his judgments, and his commandments, alway. Deuteronomy 11:1
Be ye mindful always of his covenant; the word which he commanded to a thousand
generations ... an everlasting covenant. 1 Chronicles 16:15
Thou art near, O LORD; and all thy commandments are truth. Concerning thy testimonies,
I have known of old that thou hast founded them for ever.
Thy word is true from the beginning: and every one of thy righteous judgments endureth for ever.
God will curse you if you don't obey his commandments
Behold, I set before you this day a blessing and a curse; A blessing, if ye obey the
commandments of the LORD your God, which I command you this day: And a curse, if ye will
not obey the commandments of the LORD your God.
Keeping the commandments is the whole duty of every human.
Fear God, and keep his commandments: for this is the whole duty of man.
Jesus instructed his followers to obey all of the commandments.
Till heaven and earth pass, one jot or tittle shall nowise
pass from the law, till all be fulfilled. Whosoever therefore shall
break one of these least commandments, and shall teach men so,
he shall be called the least in the kingdom of heaven. Matthew 5:18-19
It is easier for heaven and earth to pass, than one tittle of
the law to fail. Luke 16:17
And even Paul seemed to agree with Jesus on this (sometimes).
Do we then make void the law through faith? God forbid: yea, we establish
the law. Romans 3:31
No, they were only temporary.
After the birth of John the Baptist the laws no longer applied.
The law and the prophets were until John [the Baptist]: since
that time the kingdom of heaven is preached. Luke 16:16
People are justfied by faith. The law doesn't matter.
Therefore we conclude that a man is justified by faith without the deeds of the law.
If you've got grace, you don't need to obey the law.
