This is a brilliant piece that recognizes that life is more complicated than we generally think. We make more excuses for sin than we realize. We compartmentalize our failings into an explainable category while we attack others for the morally equivalent failing.
Read the whole post here, but I couldn't help but post Tim Challies' conclusion:
The second glance logic assumes that we are going through life in a morally-neutral or morally-upright posture so that there is really no connection between the first glance and the second. The reality is, though, that the second glance has often already been decided long before the first.
