Psalm 21:9 NIV
 When you appear for battle, you will burn them up as in a blazing furnace. The Lord will swallow them up in his wrath, and his fire will consume them.
Remember that God is at work in your lives and He is stoked about you as I mentioned in my earlier post from yesterday.
Anyway, what I mean is Jesus Christ fights your battles for you and I and won the victory when he died on the Cross.
Here is what I mean:
Psalm 21:11-13 NIV
 Though they plot evil against you and devise wicked schemes, they cannot succeed.  You will make them turn their backs when you aim at them with drawn bow.  Be exalted in your strength, Lord; we will sing and praise your might.
So don't worry about life because though it looks like we need to fight and win, remember when you were lost Jesus Christ won the battles with his death on the Cross!
Victory is yours, you just need to accept the invitation of Salvation.
