Here (urtext) Jesus is talking about how God is the origin of miracles and how God's POWER is unlimited, how the power of God produces miracles through you and how they extend to everyone not just yourself. "A call for help is GIVEN help".
Again this has nothing to do with a so-called "shift in perception", because the power of God acts above and beyond our own limitations, and beyond perception entirely. Miracles, sourced in and BY God, transcend perception entirely and cannot have anything to do with perceptual changes or small corrections of thought.
In a previous section Jesus also speaks of how a miracle is evidence that an entirely other 'world' is being brought to this one, as evidenced by the complete lack of respect for the order of difficulty or ego hierarchies.
