One of the doctrines of devils that has been taught in the church is “You can never keep the commandments ”
This is based on:
Galatians 3:11 KJVS
 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
(Justified = to render righteous)
We can never earn our salvation nor be righteous by keeping the Law. But there Is One who perfectly kept the Law. This is what qualified Him to be our Pascal Lamb. (To be the ultimate sacrifice that would wash away our sins)
When I received His sacrifice in my stead, and accepted Him as my savior, was baptized in both water and The Spirit, He then wrote His Laws on my heart.
We say He came to live in me.
If He truly lives In me, and “Philippians 4:13 KJVS
 I can do all things through Christ which strengtheneth me.”
Then I can Now keep the Commandments.
Not to earn anything, or to justify anything, but simply because it is the Right way to Be. (Be, not act) To show Honor to the King.
John 14:15 KJVS
 If ye love me, keep my commandments.
You have heard, “They that live by the sword shall die by the sword.” (Is it Biblical?)
I say, “They that live by the Law shall live eternally by the Law.”
He is the Law, and when He returns, and all doctrines of devils are silenced, then living by the Law will be the Only acceptable way.
Might as well get used to it.
