People really need to know that fulfill doesn't mean destroy...
Amen.
It was the handwritten document which was used as a basis of judgement (thus dividing us further away from God as inferred by the word "enmity") that was abolished.
Ephesians 2:15 "Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace.."
Thus we see why James counseled so strongly that those whose consciences were compelling them to yet observe parts of that Old Law ought to refrain from judging others on the basis of that Old Law.
James 2:12-13 "So speak ye, and so do, as they that shall be judged by the law of liberty. For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment."
James 4:11 "Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge."
James 3:13 "Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.
14 But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
15 This wisdom descendeth not from above, but is earthly, sensual, devilish.
16 For where envying and strife is, there is confusion and every evil work.
17 But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy.
18 And the fruit of righteousness is sown in peace of them that make peace."
This was the very reason God gave that handwritten law to man. God knew that is how man would use it. Every man would say to himself, "I know the law, for I have read and studied it and am not like those who do not care as much as I to do so!" And thus that law in the hands of man would fan mans' pride to amplify mans' pride so that it could then become clearly seen, seeking to control everything outside of themselves whilst believing that they were special.
What did it result in? Matthew 9:36 "But when he saw the multitudes, he was moved with compassion on them, because they fainted, and were scattered abroad, as sheep having no shepherd."
That is what God knew it would result in. Thus thru that the mans' flesh abusing that handwritten law God created many who could see that there was something wrong. They would then want to know, "Why did it not work?"
Enters Christ Jesus with the answer and the formation of a new and better covenant.
Compare what I wrote here to Romans chapter 14. That is the main chapter of Paul's writings which most loudly highlights this.
