It can't be bought because it's worth more than the whole world. God only asks us to do His will, not work that hard. What makes it worth so much is that it's never easy, because we're afraid, and would rather not do it for many reasons. We don't want to imitate the Jesus who overturned the thieving money changer's tables and chased out the sellers of over priced sacrifices from the temple, knowing the effect it would have on the chief priests on the take. We are called to transform the Chief priests, Pharisees, sadducees, scribes, and lawyers of our day, and we don't want to, especially if we're doing all right with the status quo, as most are in this country.
People look at reformers as odd-balls, to say the least.
Street people sometimes have a better grasp of what's really going on. Breaking the law or copping out on doing God's will, which is never ever to sin, naturally brings guilt to the sensitized conscience, and must be dealt with in one way or another, or it will cause serious mental or emotional problems. Rationalizing works with most. And they say, keeping the commandments leads to rigidity of behavior, but even if true, it's better than the consequence of sin. All this requires elimination of conscience and ignoring of the effects of sin on ourselves and others, and the damage it does to our relationship to God.
