A old proverb says,
"It is good to be brave, but it is also good to be careful. If you are
careful, you will not get into situations that require you to be brave." DISCRETION is the quality of behaving or speaking in such a way as to avoid causing offense or revealing private information. It is a Middle English word in the sense of discernment - the ability to judge well. Discernment is perception (to be aware of something through the senses) in the absence of judgment with a view to obtaining spiritual direction and understanding.
If I am discerning, I have the ability to see beyond what I see. With
discretion, I can wisely and empathetically decide what to do or say in a
situation.
In 2 Kings 6 the king of Aram was about to siege the Jews. Each time he made a move, Elisha the prophet warned the king of Israel.
Elisha was so accurate that the king of Aram thought he had a spy in
his ranks! Frustrated, he attempted to send his armies to capture
Elisha. As the Arameans were approaching, Elisha's servant
cried out, "Oh no, my lord! what shall we do?" (15) Elisha replied, "Don't
be afraid. Those who are with us are more than those who are with them," and Elisha prayed, "Open his eyes, LORD, so that he may see." Then the LORD opened the servant's eyes. He looked and saw the hills full of horses and chariots of fire all around Elisha. As the enemy came down, Elisha prayed to the LORD, "Strike this army with blindness."
So He struck them with blindness as Elisha asked, and he led them into
an ambush. The LORD gave the victory into Elisha's hands! He did not
even have to kill the army, he just exposed them and sent them home with
food and drink. Aram's armies stopped raiding Israel's territory.
Discernment means the LORD has opened your eyes. Discretion means you
know what to do when what you see isn't really what you're looking at!
