God will be all of our Judges nothing we can hide from Him Ecc12:13-14 James2:11-12
You obviously don't understand James 2:11 -12 - because you left v 2:10 from your post which sets the context for 2:11 &12. They say
that if you want to be justified by law then you had better have satisfied all of THE LAW perfectly. Judged by the law of Christ which means not trusting in our works of law
Ecc pertains to the OC, not the NC. Those saved by Christ and placed under the NC have satisfied it by God's work, not man's.
[Jas 2:10-12 KJV]
10 For whosoever shall keep the whole law, and yet offend in one [point], he is guilty of all.
11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
12 So speak ye, and so do, as they that shall be judged by the law of liberty.
