Philippians 4:6

Do not be anxious or worried about anything, but in everything (every circumstance and situation) by prayer and petition with thanksgiving, continue to make your (specific) requests know to God. 

Faith turns to God about a problem and doesn’t let anxiety take over. Anxiety makes us dwell on the problem, and we need to answer the problem with the solution in prayer. If we let the devil bombard us with worrying thoughts and don’t stop them, we will not see victory. Prayer, petition, and thanksgiving are key to our specific requests.
