God talk to us in many ways. in the past He talk through Prophets (Hebrew 1:1). But People did not listen to them. 

     Then He talk through His Son Jesus Christ but then deny His words ( Hebrew 1:2; John 10:30-40) and they took stone against Him.  

     Then God write or put His law into our Hearts and Minds (Hebrew 10:16). As He said through Jeremiah in 31:33.

     I want to encourage you to obey God whenever He whisper in Your Heart through Holy Spirit or His Son Jesus Christ.
