Do Christians have a duty to keep God's commandments?
John 14:15
"If you love me, keep my commandments"
Ecclesiastes 12:13
"Now all has been heard; here is the conclusion of the matter: Fear God and keep his commandments, for this is the duty of all mankind".
Once you say you have a duty to keep the Torah Law then you better keep them perfectly without fail, no not even once fail to do the law.. You and works salvationist cultist like yourself who preach that one must keep the Law to be saved will stand before the LORD one day and you will be shown where you broke that law and you will be shown the Eternal Lake of Fire...
Salvation is attained by Believing Jesus and trusting in the Atonement He secured on the cross, that it pays the penalty of ones transgressions against His Law.. There is NO other Way..
