In a sense, works justify justification. They are also inseperably linked to it, follow it, and flow forth from it.
Also, since when did good works get a bad rap?
Probably since we deduced from the Protestant Reformation that Judaism and Catholicism are both merely morality-based expressions and attempts at a relationship with the God of the Bible.
Or, probably since we have set the post-Enlightenment human psyche as the goal and end of all thinking. When this happens, human motives behind works take a seat on the throne.
But all of this - works, motives, justification, sanctification, salvation, etc - all of this takes its proper order and place when our focus is correct. Our focus is God Himself [2 Cor 3.17-18]. This means we must "hear with faith" [Gal 3] and walk by the Spirit [Gal 5, Rom 5-8] as we have our eyes perpetually fixed on what God has done in Jesus.
