It is not temporal good works that are in view in that verse.
For the desire to do what is good is with me, but there is no ability to do it. ... For I know that in me, that is, in my flesh, dwells no good thing. For the desire to do good is present within me; but how to work out that which is good, I do not find. ... Thanks be to God, through Jesus Christ our Lord! Romans 7:18 and
For it is God who works in you, both to will and to work for his good pleasure. Phil 2:13
Remember all those 'crowns' we receive will be cast at HIS feet, HE ALONE is worthy.
And just to make sure you understand man's inablity and total worthlessness outside from Christ........there are no crowns for 'good works' As scripture says, mans' works are as filthy rags (Is 64:6)
