At resurrection everyone's work will be tested by fire - the revealing fire of God!! Let your foundation be sure - Christ Jesus!! 

The work is not the reason for your salvation - Salvation is by Grace alone, through Faith in Christ Jesus. This work is not achievements it is the intents of the heart.

The reward for work is only for believers - good men; Only those who have the in-dwelling spirit of God are good, every other no matter how good they are in this universe if they have not believed the Christ are not good before God.

Shalom!!
