“It is impossible to convert or persuade by mere dogmatizing or ranting. No amount of mere statement, no ‘spoon-feeding’ (as every teacher knows) will achieve this end. There is nothing for it but to sow ‘seed-thoughts’ – to set something germinating in the hearers. If they respond, they begin to be ‘inside’, they ‘come for more’; if they pay no heed – or for as long as they pay no heed – they are self-excluded. Hence the use of parables.” (C.F.D. Moule, The Birth of the New Testament, pp 150-151)
