We are God's kingdom and priests. Thus, you must make every effort in all that you do for God, so that you can confidently present your ability before God.
There should not be any negative thoughts in God's kingdom. And we cannot tolerate any cheating; unlawfulness is also unacceptable. Those who do such things will eventually be cast out (of God's kingdom).
We cannot do things that would be criticized by the world. Rather, we must become the light of the world.
