He is still powerful enough to give life and to take it. He is greater than our thoughts and imaginations—not confined to a DaVinci painting or a religion by any moniker. He is the Alpha and Omega, the Beginning and the End. He is able to forgive and restore more deeply than we can imagine while being equally capable of exacting more justice than mockers like the ones in the poster, and sinners like all of us, can conceive.
I don't fear for His reputation, but for the men and women who think they can affect it by mocking him—those who think that because there was no bolt of lightening that struck when the digital camera clicked and captured their image, justice will not be had on the unrighteousness they pervade.
This is lawlessness—the natural result of rejecting God's law. It's progressive in nature. It begins with the misguided notion that morality is intolerance; that rejection of certain forms of behavior is bigotry. This worldview leads to throwing off all restraint and "tolerating" anything and everything.
Mockers beware. For God will not be mocked. Meanwhile, take a good hard look and see if the natural progression of "tolerating" everything is producing the world in which you really want to live.
