Pastor Peter W. Marty preaches on Exodus 32:7-14. To have a change of mind or a change of heart when we are wrong,  mistaken, or blind to a very important truth is a beautiful thing. To alter our course or reverse our ways of thinking when we have wronged others, disrespected them, or been too certain of our own certainty is a magnificent move that is open to all of us. Faith is all about change; change is a constant companion.
