Work should be the servant of our faith and not its controller.  Like life, it should be an expression of our faith to the degree we are able to express it without causing offence to another.

Even if our faith can only be expressed in our heart's attitude it must still be expressed in the attitude we have towards things.

Remember!  God does not judge you on what you do but on the attitudes you have in your heart towards the thing you do.

The Bible says how we think in our heart will be who we are.
