Gal 3:10 For those who rely on the works of the law are still under the curse, for as it is written, cursed is everyone who does not practice everything which is written in the book of the Torah. (Deut. 27:26)
Curses from Mount Ebal
Deu 27:9-26 And Moses and the priests, the Levites, spoke to all Israel, saying, Keep silence, and hear, O Israel: Today you have become the people of YAHWEH your Elohim. Therefore you shall obey the voice of YAHWEH your Elohim and do His commandments and His statutes which I command you today. And Moses charged the people the same day, saying, These shall stand on Mount Gerizim to bless the people when you have crossed over the Jordan: Simeon, and Levi, and Judah, and Issachar, and Joseph, and Benjamin. And these shall stand on Mount Ebal to curse: Reuben, Gad, and Asher, and Zebulun, Dan, and Naphtali. And the Levites shall answer, and shall say to all the men of Israel with a loud voice: Cursed is the man who makes a carved and cast image, an abomination to YAHWEH, the work of a crafts-man's hands, and who sets it up in a secret place! And all the people shall answer and say, Amen! Cursed is he who dishonors his father or his mother! And all the people shall say, Amen! Cursed is he who removes his neighbor's landmark! And all the people shall say, Amen! Cursed is he who makes the blind to wander out of the way! And all the people shall say, Amen! Cursed is he who perverts the judgment of the alien, the fatherless, and widow! And all the people shall say, Amen!
ursed is he who lies with his father's wife, because he uncovers his father's skirt! And all the people shall say, Amen! Cursed is he who lies with any kind of animal! And all the people shall say, Amen! Cursed is he who lies with his sister, his father's daughter, or his mother's daughter! And all the people shall say, Amen! Cursed is he who lies with his mother-in-law! And all the people shall say, Amen! Cursed is he who strikes his neighbor secretly! And all the people shall say, Amen! Cursed is he who takes a bribe to strike a life, to shed innocent blood! And all the people shall say, Amen! 26 Cursed is he who does not carry out to do all the Words of this Torah, to do them! And all the people shall say, Amen!
Jas 2:8-13 If you truly fulfill the royal Law according to the Scripture, "You shall love your neighbor as yourself," you do well. (Lev. 19:18)
9 But if ye have respect of persons, ye commit sin; and ye are convicted by the Torah, as transgressors of the Torah.
10 For whoever shall keep all the Torah, even though he fail in but one statute, he has become guilty as to all of it. (Deut. 27:26)
11 For He who said, You shall not commit adultery, also said, You shall not murder. But if you do not commit adultery, but commit murder, you have become a transgressor of the torah. (Ex. 20:14, 13; Deut. 5:18, 17; Deut 27:26)
12 So speak and act as men being about to be judged through a Law of liberty.
13 For judgment will be without mercy to the one not showing mercy. And by mercy you will be raised above judgment.
I agree 100% "that all have sinned".
Our root of our faith is the precious perfect sinless lamb of God and His passion to save all who will receive His Work on the cross.
However, we may disagree to what our fruit of our faith entails. For me, 1Jn 3:4 Everyone practicing sin also practices lawlessness, and sin is the breaking of the Torah.
Mat_7:23 And then I will declare to them, from everlasting, I never knew you; "depart from Me, those working lawlessness!" (Psa. 6:8)
Tit_2:14 who gave Himself on our behalf, "That He might redeem us from all lawlessness and purify a special people for Himself, zealous of good works." (Psa. 130:8; Eze. 37:23; Deut. 14:2)
Heb_1:9 You have loved righteousness and hated lawlessness; because of this, YAHWEH, Your Elohim, has anointed You with the oil of gladness beside Your fellows."(Psa. 45:6, 7)
Jas 1:12 Blessed is the man who endures temptation, because having been approved he will receive the crown of life which YAHWEH promised to the ones loving Him.
Mat_22:37 And Yahshua said to him, "You shall love YAHWEH your Elohim with all your heart, and with all your soul, and with all your mind." (Deut. 6:5)
Mar_12:30 and you shall love YAHWEH your Elohim with all your heart, and with all your soul and with all your mind, and with all your strength." This is the first commandment. (Deut. 6:4, 5)
Luk_10:27 And answering, he said, "You shall love YAHWEH your Elohim with all your heart, and with all your soul, and with all your strength, and with all your mind," and "your neighbor as yourself." (Deut. 6:5; Lev. 19:18)
