God’s Law, His morals, have always existed and still exist. Scriptural definition says God can not change and that includes the Word and Law. In fact to get rid of the Law of God, gets rid of Christ by scriptural definition. This is why the anti-Christ has been teaching that God’s Law is done away for the last hundred years or so.
One morning in Sunday school the teacher said, “There was no law before Moses”. This was my response.
Genesis 26:5 "Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws."
They also like to say the Law is now done away since Christ. Paul disagreed. Notice the verb tense Paul used.
1 Timothy 1:8 "But we know that the law is good, if a man use it lawfully".
