This is an awesome formulation by Paul Blackham of the Biblical definition of sin:
Sin is any and every action or thought or word or desire that opposes the actions, thoughts, words and desires of the most holy God who made us and will judge us. Our attitude to Jesus reveals how we stand because Jesus is the definition of the actions, thoughts, words and desires of the most holy Father.
Good, isn’t it?
ps. does anyone remember the reference for this quote, i.e. in what sermon he said this?
