The very fact that you struggle with this would seem to indicate that you are sensitive to this and are careful to evaluate your motives. When your sinful nature sticks his head above the water and "blows his own horn," you are quick to push his head back under the water.

To further help you in this struggle I would suggest that you remember it is more important to spend time looking at the cross and less important to spend time looking at our good works. Certainly there is a place for analyzing our Christian lives. But the more we focus our attention on Christ, the more we will naturally do good works without even knowing it. We note that when the believers in the Parable of the Sheep and the Goats were confronted with their good works, they were surprized. They were simply doing them out of love for their Savior, often without realizing it.
