If we say we have faith, but no works follow, that is clear evidence that our faith is not genuine. - RC Sproul

“If we say we have faith, but no works follow, that is clear evidence that our faith is not genuine. True faith always produces real conformity to Christ. If justification happens to us, then sanctification will surely follow. If there is no sanctification, it means that there never was any justification.” 

– R. C. Sproul, The Holiness of God
