I remember that while reading the Left Behind series, I was amazed at how people's hearts were so hardened. All the horrendous things that were described as going on around them, and these people just explained everything away. It is happening now, in real life. Things are happening that totally line up with Biblical prophecy, and people are brushing it aside with the standard, "Things have always been like this" reply. I honestly believe that this is what God meant about things being as they were in the times of Noah. Man's "intelligence" is blinding him to what is happening. People have pushed God so far out of their lives that He doesn't even factor into their equation when explaining today's events. There is a scientific explanation for everything, apparently. Those who have opened their hearts to Jesus have had their eyes opened, thus allowing them to see things for what they are, God's final warning to mankind. Those who have hardened their hearts will not see, because they choose not to.
Let us thank God that He chose us and loves us and that we were able to accept and receive His gift of Grace. While the rest of the world remains blind, our eyes will remain open as we wait for the trumpet to sound...
"Jesus said to them all: "If anyone would come after me, he must deny himself and take up his cross daily and follow me. For whoever wants to save his life will lose it, but whoever loses his life for me will save it."
— Luke 9:23-24 (NIV)
