We have this tendency to think of good as things like helping the poor, and yes, this is good, but, this is not the same as producing fruit. For what good is it when we have made the poor comfortable here, only to spend eternity in discomfort. This is why, or partly why, our works are meaningless. Our good works apart from Jesus are meaningless. Only when our works are the result of our faith in Christ do they become fruitful. If we, the branches, are not connected to the Vine, we are a dried up thing and cannot produce fruit. We produce fruit when we bring people to eternal comfort.
