I will also add your premise is flawed...God has a perfect memory and has the ability to completely forget....their sins and iniquities I will REMEMBER no MORE...the memory of the wicked shall be FORGOTTEN...It is NO problem for Jesus to say that he never KNEW someone based upon the simple fact that they did not trust HIM in faith and he NEVER acknowledged them as children......
You need to use the whole context of scripture there as it shows these are repented and confessed of sins that our forgotten, not speaking on those who remained deliberately sinful.
The scriptures you are taking this from is Hebrews 8:12, 10:17, and also was stated in Isaiah 43:25 as these are sins that have been given remission for by His blood. These scriptures has absolutely nothing to do with Jesus telling a disobedient servant He never knew them, and is taking out of context to even compare it to two separate situations.
God created all things the good people and the bad people, so He knows all of His creations.
Saying He never knew somebody He created is a term of denial, denying them for denying Him !!!
