I feel like God has been teaching me this for years (via Tim Challies):
If we are going to follow in such a way that we parse every word and appeal to every loophole, we should expect our followers to parse our every word and to pursue every loophole. If we are going to follow formally, to go through the motions but with grumbling and complaining, we should expect our own followers to grumble, to complain, to do no more than the minimum. If we are going to follow the letter while ignoring the spirit, we should not be shocked when those we lead likewise follow the letter but violate the spirit. We are all natural imitators, so that the way we follow begins to look a lot like the way they follow.
