By all means keep the law and as Jesus has said - every jot and tittle.
But be careful and diligent...
James 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
Deuteronomy 27:26 Cursed be he that confirmeth not all the words of this law to do them. And all the people shall say, Amen.
Once you fail the law curses and kills.
2 Corinthians 3:6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
7 But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
8 How shall not the ministration of the spirit be rather glorious?
Hebrews 4:9
9 So then, there remains a sabbath rest for the people of God;
10 for whoever enters God's rest also ceases from his labors as God did from his.
11 Let us therefore strive to enter that rest, that no one fall by the same sort of disobedience.
Matthew 11
28 Come unto me, all ye that labor and are heavy laden, and I will give you rest.
29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
30 For my yoke is easy, and my burden is light.
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Not Moses.
John 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ.
Amen.
