Jesus lived in a historic time period in 1st Century Palestine.  Do you think he would use the same expressions to describe God today?  Don't think so.  Israel no longer has a Temple, no longer has sacrifice as a major part of its worship.  

Every age has had people who truly sought out God, not only as law-giver, but as friend, lover, life-giver.  They are the mystics---and we have their writings to read and guide each new generation.  Each generation stands on the shoulders of the other---in trying to truly Know, Love, and Serve God in their time and in their age.
