The mind itself is a potent instrument for change, the only one there is.
All change must take place in the mind first,
for all action is a result of thought and the resultant impulse or motivation.
Miracles are expressions of Love; thus they bless the giver and receiver equally.
If you would receive the power of miracles into your life, you must reach a state of miracle mindedness. This requires faith, faith in the unseen, faith in the Holy Spirit.
He makes miracles available to you if you ask sincerely with an open mind and a pure heart.
