I recently listened to a talk by J D Hall over at Worldview Weekend. He was speaking about how some object to the call to obedience to the commands of Christ with the rejoinder "but that's law", to which J D replies - no that's worship.
He then makes the telling point "law is doing those things in order to obtain merit or favour with God"
Yet Jesus said "If you love me you will follow my commands".
something worth pondering
