2nd Chronicles chapter 20. What's the problem?

King Jehoshaphat of Judah and Jerusalem heard that a vast and huge army was coming out against him and his people. How he responded to a seemingly impossible war is how I want to respond when I face troubles of any kind. He did the following:
1. INQUIRE: he inquired God first and foremost.
2. FAST: he fasted before the Lord. A way of saying not me God but you.
3. ONENESS: he called his family of God to join in prayer.
4. HUMBLE: the people humbly came before the Lord recognizing It is by God's power and strength and not their own.
5: TRUST: They trusted God. This is the hard part for me. It's not always easy for me to trust God particularly in what seems like an impossible situation.
6. DELIVER: in God's due time He will intervene in our situation.
7. PRAISE and THANKSGIVING: this is another area where I have room for improvement. All Judah praised and thanked God before his Deliverance came and after. I want to be able to praise and thank God before the Deliverance comes as a way of knowledging my faith and trust in him, but also praise and thank him when he does intervene and answer.
