WHY 3 AM

Personal and Scriptural references to why we are sometimes woken up at 3am? Why does it seem to be the perfect time for the Lord to lay things on our heart to pray? Are you a new Christian that has been woken up at that time before? Do you lay in bed trying to go back to sleep, and you cant, you feel like you must do something but you don't know what. Seek the Lord, hear what the scripture tells us. Listen to personal examples. What does God tell us to do?
