"He [Jesus] replied, '…I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there' and it will move. Nothing will be impossible for you.'"1
Grant Frazier said, "Life is full of obstacle illusions." He's right.
Instead of seeing obstacles as opportunities to grow, negative people see them as obstacle illusions. They see them as mountains too high to climb and use them as excuses to hang on to if they don't want to act responsibly and grow up and therein become stronger, healthier persons.
It's all in their attitude of mind—their negative thinking—and they allow their problems to have a crippling effect in their life. They are faith-less!
On the other hand, positive people are faith-full. They see every obstacle, not only as a challenging mountain to climb and conquer, but as an opportunity to grow and become stronger, better, healthier persons. When faced with an obstacle (as another has suggested), they don't tell God how big their problems are. They tell their problems how big their God is!
Neither do they allow past failures to defeat or depress them. And when the devil comes to remind them of their failures, they remind him of his future! Thus ends their discussion with the devil!
Suggested prayer: "Dear God, please help me to commit and trust every obstacle in my life to You and give me the faith to 'climb every mountain, ford every stream, follow every rainbow until I reach my dream'2—or rather, until I reach Your 'dream' (purpose) for me. Thank You for hearing and answering my prayer. Gratefully, in Jesus's name, amen."
