Mark,
I swallowed the same error Mr Potts is teaching here years ago for lack of available sound teaching. You cannot read Psalm 119 and accept his conclusion. Galatians speaks of the Judizers who were saying that you must become a Jew to become a Christian and be circumcised etc. Paul is not speaking of forgetting the commandments there! I am praying for you Mark, that you will not be deceived by this incorrect handling of God's Word, even denying the Lord's own words.
