Charles Haddon Spurgeon said this quote

Is not the gospel its own sign and wonder? Is not this a miracle of miracles, that 'God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish'? Surely that precious word, 'Whosoever will, let him come and take the water of life freely' and that solemn promise, 'Him that cometh unto Me, I will in no wise cast out,' are better than signs and wonders! A truthful Saviour ought to be believed. He is truth itself. Why will you ask proof of the veracity of One who cannot lie?
