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?
When you know that something's going to happen, you'll start trying to see signs of its approach in just about everything. Always try to remember that most of the things that happen in this world signs. They happen because they happen, and their only real significance lies in normal cause and effect. You'll drive yourself crazy if you start trying to pry the meaning out of every gust of wind or rain squall. I'm not denying that there might actually be a few signs that you won't want to miss. Knowing the difference is the tricky part.
