We often here these verse quoted in Church or by believers for their encouragement they give.  Actually, when I think about Jesus’ teachings these are not mediocre prophetic words.  Firstly, it is the Holy Spirit Who spoke these words to us. This means that these words should be taken very seriously indeed. 

God is Going to write His Laws on the tablet of our hearts through the work of Our Lord Jesus Christ Hebrews 10. 11-18
