So, how many times have we heard the name (i.e., the power) of Jesus invoked and approval of Jesus claimed by people who don't/won't live according to his ways?
I was driving my car and thought of this metaphor. If Jesus is just my hood ornament then the destination of my car is irrelevant to him and the way I drive is, too.
However, if Jesus is Lord and God, then my destination and my methods of getting there are to be found within his precepts and purposes. My feelings, thoughts, ideas, choices and actions are subject to God Almighty. Otherwise, the claim to worship God is an empty claim of vacuous words and vain "faith."
Jesus isn't even "my co-pilot" in this metaphor. The Holy Spirit indwells me and I drive where and according to the guidance of Godself. If I'm in the office, I "drive" my relating to others, my ethics and my work performance by, for and to God. If I'm at home, I "drive" my relationships with my spouse, children, neighbors and community knowing the love of God as my primary goal, focus and strength.
