In Genesis when God said, "Let there be light," light came out of the darkness. According to Paul in 2 Corinthians 4:6, this is the same God Who "shines in our hearts." The "light" of Genesis is the
"shines" of 2 Corinthians, and the "darkness" of Genesis is the "our hearts" of 2 Corinthians. The power is unrejectable.
