“Exposition identifies the traps we must avoid. The two main pitfalls are forgetfulness and disloyalty. The forgetful expositor loses sight of his text when he follows his own ideas and forgets to follow what the text says. The disloyal expositor appears to stick to his text, but strains and stretches it so that it means something quite different from its original and natural meaning”
Stott, The Challenge of Preaching, p. 29
