James 1:8 NIV
He is a double-minded man, unstable in all he does.
We all know people like this. They act one way while in your presence, but completely different around others. What I find interesting about this is that it is almost universally abhorred, yet it is also almost universally practiced. Why is it that we are so quick to judge others based on their actions, yet we demand to be accepted based solely on our own honorable intent?
