I believe in the power of positive confession. We understand from God's word that the world was formed through His word. Words have both creative and destructive abilities, that is why we have to be mindful of what we confess with our mouths. Anything is achievable when we continually say it. The more we say it, the more we believe in its possibility. I like the last part, "I am fully convinced I can overcome any mountain, regardless of its height or width". Thanks @topcoach for that great piece
