Mark 5:36

​"Overhearing what they said, Jesus told him, “Don’t be afraid; just believe.”
    Mark 5:36

When we pray for anything, you have to pray like you eat, at a minimum. 

As you eat more than once a day and throughout your day even some snacking. You must pray this way throughout your day, however with those prayers, you must Believe (before) you pray.

You must have a heart of faith along with your prayer requests. You must  believe that what you're asking the Lord for will come to be, as long as it's in his will.

Believe, pray, walk & speak in your faith.
