One of my favorite quotes.

"Do not withhold good from those to whom you should give it If it is within your power to help."—(proverbs:3:27)[NWT Bible]

It reminds me of if you have the power to help to change or any possibility to take the risk to take a leaping chance. Power is a great responsibility and the consequences of those action are at their utmost, So imagine If you did nothing. you could have changed the result, if you realized you had that power to help. It means much i guess to never judge the ability of ones self inner power.
