Charles H. Spurgeon on Psalms 24:3

It is not he who sings so well or so many Psalms, nor he who fasts or watches so many days, nor he who divides his own among the poor, nor he who preaches to others, nor he who lives quietly, kindly, and friendly; nor, in fine, is it he who knows all sciences and languages, nor he who works all virtuous and all good works that ever any man spoke or read of, but it is he alone, who is pure within and without. Martin Luther.
