Yes, it probably is.
This is a genuine church sign (I'm correcting first post, which said it was a spoof - it's not). It's from a library of such signs held at www.churchsign generator.com (hit their link to "real church signs").
This one certainly expresses the view of some Christians, including, probably, Martin Luther: "Faith must trample all reason underfoot".
However, it's possible to construct fake signs too. If such childish humour appeals to you (as it does to me) go to www.churchsigngenerator.com

What "reason" do I have to believe the sign?
(or Martin Luther)
Yes, that's why I first thought it a fake. But actually, it comes from their library of genuine signs. Check out "Real church signs" at the top of their home page.
What do you expect from a woman? She doesn't even realize the damage she's doing? Read Eve...
God calls us to reason with him about our sins. Isaiah 1:18
“Come now, let us reason together, says the Lord: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool.
