When David in the Old Testament was only 29 years old, he gathered around him 600 men who were in debt, discouraged, and discontented — and he molded them into a mighty army. They claimed victory after victory for Israel. 
The Bible gives an account of when David and his army of 600 men were coming back from another victory. They were maybe ten miles from home when they saw black smoke on the horizon. They pick up the pace, and when they get about two or three miles away, they realize it’s coming from their city. Their anxiety turns to panic, and they run to their city. It was a horrible sight. The Amalekites had raided the place, and destroyed it. They kidnapped the women and children, they had taken all the possessions they wanted, and the rest of the stuff, they burned.
It was a dark hour in David’s life. The Bible says that David and his men wept until they could weep no more. But even at so young an age, David’s life had produced endurance. He knew that, with the power of God within him, adversity could not master him. God would master adversity. The answer wasn’t to give it to adversity; it was to step out in faith.
David got together those 600 men. They might be outnumbered, five-to-one! 
But David told them, “We’re not going in our own strength. We’re going in the strength of our almighty God.” The Bible says they went out and fought with a new fervor. They fought with a new determination. And the Bible says they wiped out the Amelekites that day. They recovered all the women and the children, and everything they had lost.
I want you to remember that when David was sitting there on the ash heap of his ruined city, in that dark hour, he was just 72 hours away from the greatest victory in his entire life.
You may be facing terrible adversity; you may be going through great trials. But if you keep your faith in God, and trust God’s power and strength within you, you could be close to the greatest victory that you’ll ever see. You see, it’s the struggle that gives us strength, and your victory could just be right around the corner.
