Proverbs 3:25,26

Do not be afraid of sudden terror,

Nor of trouble from the wicked when it comes;

For the Lord will be your confidence,

And will keep your foot from being caught.

We may not be able to control our circumstance, but we can control how we react to it.  If we turn to God when trials and tribulations happen and confess His word we will raise our shield in defense against the enemy.  What may look like a tidal wave in front of us can be reduced to a puddle when we pray in faith to Jesus.  Confess the word and not the situation and we overcome and walk through the situation in faith.
