The 8th commandment still says, "Thou shalt not steal." So if we are working on our income tax and we start to reason, "This might not be a valid deduction, but I work hard, and the government is corrupt anyway. They'll never check on it," we are not living in the new resurrection life Jesus gave us as a gift when we believed in him. Before we piously sing his praises on Sunday morning, we need to go back and eliminate the false deduction. As believers we need to stop attacking the sin we see in our culture while not dealing with the sin in our own lives.
