I should point out that there is value in doing the right thing even if our motives are not entirely pure (which they will never be in this lifetime). I’m certainly not saying that one should sit on the sidelines until something can be done with perfect motives.
This morning I read the story in Mark 11 of Jesus cleansing the Temple. He was angry with those who were using worship at the Temple for their own gain. Since most of us haven’t been guilty of selling birds or running a currency exchange in the back of the church, we are afforded the opportunity to smugly look down on those rascals that Jesus tossed out.
