Yes, believe it or not I understood the expression. But the problem is that because you are relying on such non-accurate expressions and appeals to emotion, you are unable to demonstrate your claims in an objectively verifiable manner. A Hindu, Muslim, Sikh or Jew could also tell us to "see with our hearts" to claim that THEIR particular religious beliefs are the most valid in the world rather than yours. You believe in your religion. They believe in theirs in equal measure. I choose not to believe any and demand they provide an objective demonstration instead.<quoted text>
Open your heart is just an expression. It means to let God fill you with the Holy Spirit and love.
So far no religious person on the planet is capable of doing that.
