This is how you should explain all the passages of Scripture which talk about works. God wants us to let the righteousness that we have received in faith break forth, demonstrate itself, and benefit others, so that false faith becomes known and rooted out.  God gives no one His grace so that it may lie down and be of no benefit, but so that it would give a good return, and through knowledge and outward public demonstration entice everyone to God. Christ says, “Let your light shine before people, so that they see your good works and praise your Father in heaven” (Matthew 5 [:16]). Otherwise it would be like a hidden treasure and concealed wisdom, and what benefit are either of them?  Martin Luther
