for the battle in not your's but God's

I was reading this portion in The Bible this morning and wanted to share the encouragement I found. May it be a blessing to all of you as well.

2 Chronicles 20: 15b, 17, 20b

v 15b Be not afraid nor dismayed by reason of this great multitude; for the battle is not your's, but God's.
v 17 Ye shall not need to fight this battle: set yourselves, stand ye still, and see the salvation of the Lord with you
v 20b  Believe in the Lord your God, so shall ye be established; believe His prophets, so shall ye prosper.
