Matthew 17;20-21 ....if you have faith as a grain of mustard seed you shall say unto this mountain remove hence to yonder (yonder :) place and it shall remove and nothing shall be impossible to you; howbeit this kind go not out but by prayer and fasting.

The power of the word is in your mouth! SAY-IT! And don't forget to include prayer and fasting!
Death and Life are in the power of the tongue. but don't focus on the death part, speak life.
