“I know that you can do all things; no plan of yours can be thwarted.  You asked, ‘who is this that obscures my counsel without knowledge?’  Surely I spoke of things I did not understand, things too wonderful for me to know.”
 
David

David, with the spirit of the Lord upon him, saw obstacles in his life as opportunities “that all the earth may know that there is a God in Israel” (1 Samuel 17:46).  He believed that every battle was not his own, but rather the Lord’s.  When he heard about the giant Goliath defying the armies of the living God, challenging any Israelite to combat, instead of running away in fear as many of those in the army did before him, he told King Saul, “Don’t worry about a thing; I’ll go fight this Philistine!” (1 Samuel 17:32).
      
David, a youth at the time, had no obligation to be there on the battlefield.  He was a shepherd and part-time musician for the King.  His older brother, Eliab, questioned David’s real purpose for being there, accusing him of being prideful and dishonest.  Saul told David that he was “not able to go against this Philistine to fight with him.”  Regardless of what others thought, David went into the battle confident of his Lord, “Today the Lord will conquer you” (1 Samuel 17:46)

• How often do we invite ourselves and insist upon going into the battlefield?
• How many of us see a danger, a challenge, a formidable enemy and run toward it wanting to face it?
• Instead, how many of us have delayed facing a challenge, hoping that it would go away?
• Have we missed an opportunity to show that “there is a God”?

David approached impossibilities as opportunities because he perceived the obstacles as opportunities to glorify the Lord.

Alleged ‘impossibilities’ are opportunities for our capacities to be stretched

Shadrach, Meshach, and Abednego

Shadrach, Meshach, and Abednego perceived no obstacle at all when King Nebuchadnezzar of Babylon summoned for them.

“When they were brought in, Nebuchadnezzar said to them, “Is it true, Shadrach, Meshach, and Abednego that you refuse to serve my gods or to worship the gold statue I have set up?  I will give you one more chance.  If you bow down and worship the statue I have made when you hear the sound of the musical instruments, all will be well.  But if you refuse, you will be thrown immediately into the blazing furnace.  What god will be able to rescue you from my power then?”

Shadrach, Meshach, and Abednego replied, “O Nebuchadnezzar, we do not need to defend ourselves before you.  If we are thrown into the blazing furnace, the God whom we serve is able to save us.  He will rescue us from your power, Your Majesty.”  (Daniel 3:14-17)
