Prayer
Philippians 4:6
Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God
 
Mark 11:24
Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours.
 
Romans 8:26
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express.
