If darwinian evolution is true, there is no ultimate purpose to existence. There is no right and wrong -- so we can each do as we please without having to worry about any ultimate consequences. There is no final accountability, and no ultimate justice. The universe is, ultimately, one vast, unfeeling, uncaring material wasteland where life was never intended, just happened to pop into existence, and then just happened to evolve into incredibly complex organisms that bear the (false) evidence of progression and design.
Darwinians can hold their newborn baby in their arms and say, "you are unintended and uncreated, your life is without ultimate value or purpose, and you have no more ultimate value than a slug. I love you, but that is because of a trick of unfeeling evolutionary forces that produce this illusionary emotion from purely chemical reactions within my brain. Welcome to the planet!".
For the life of me, I can't understand the enthusiasm that humans have for darwinian evolution -- you would think that it's apparent truth would sadden people rather than make them gleeful, especially when you consider how it cheapens human life and makes it inconsequential -- unlike Christianity, which testifies that humans are the apex of God's creation, made in His image, and can be restored to fellowship with Him through Jesus Christ.
You would think that rational beings would at least say, concerning Christianity, "gee, wouldn't it be great if it were true. I would really like it to be true, but, it just can't be".
Instead, darwinians and atheists regularly gloat and mock Christians who bear witness to a loving and all-powerful Creator, from whom we are estranged by sin, but restored through Jesus Christ.
Maybe it's because they like sin and prefer it to the pursuit of righteousness which follows belief in God.
Which just happens to be the Bible's witness concerning mankind.
Sounds like atheists and darwians are by their actions bearing witness to the truth of the Bible.
Now that's an interesting proposition.
And that's the way the Ball bounces.
