Then may I suggest a thorough reading of Eph. Chapter 2? Because until you understand when “time past” ended and “but now” began, you will never be able to study God’s word rightly divided. And you WILL be ashamed when you stand before Him. 2 Tim. 2:15. God would not tell us how to be approved unto Him, without showing us how to do this.
If you wish to nullify His commandments, good luck when you stand before Him.
