But you will not even need to fight. Take your positions; then stand still and watch the Lord's victory. He is with you, O people of Judah and Jerusalem. Do not be afraid or discouraged. Go out there tomorrow, for the Lord is with you! 2 Chronicles 20:17 (NLT) 

What God tells Jehoshaphat in this passage, and what he would remind us today, is this: "The battle is not yours; it's mine. You don't have to fight in it."

In other words, it's God's problem. Let him solve it.

The fact is if you are God's child, then your problems are his problems. And he's much better at fighting your battles and solving your problems than you will ever be. Your job is to trust him to work it all out. Perhaps the reason we have so many tired, fatigued, and discouraged Christians is because we think, "It all depends on me."

The day you resign as General Manager of the Universe, you're going to find that it doesn't fall apart. You can relax in faith, trusting that God is able to run things without your help.

Twice in this passage it says, "Don't be afraid," and "Don't be discouraged." When you face a seemingly impossible situation, don't be afraid and don't be discouraged. Has God ever lost a battle? No. He doesn't lose battles.

God tells Jehoshaphat, "Take your positions and stand firm." What does it mean to stand firm? It means to have a mental attitude of quiet confidence.

You stand firm on two things:

• The character of God - He's faithful. He does not bring us this far just to let us down. He doesn't bring you out on a limb and then cut off the limb. Have faith in the nature and character of God.
• The truth of his Word - God's Word is faithful. You can count on the promises found in the Bible.
