Being Salt and Light?

"The Holy Spirit gave us the power to be witnesses, not to do witnessing. And so we need a generation of Christians that understand it's not about standing on a street corner to do witnessing, but to be witnesses on the earth. To bring salt and light in the midst of our darkness. That's what God has called us to do." ~Christine Caine via Lifechurch.tv

So according to Christine Caine, we're not to go preach the gospel, we're to just exist as Christians in the world. And not to judge or call out sin, rather we need to just bring salt and light.

I guess Peter and the rest of the apostles did it wrong when they were filled with the Holy Spirit and went into Jerusalem during a festival preaching the gospel, telling the people to repent of their sins, save themselves from this crooked generation, and to be baptized and to follow Jesus.

And Paul did it wrong when he went to the Areopagus and told the Greeks not to be ignorant but to repent of their sins because Jesus would soon return to judge the world. Then he went to Corinth and tried to preach to the Jews but they wouldn't listen to him, so he shook his garments of them and said, "Your blood is on your own heads."

And Jesus did it wrong when, in the same public sermon he preached about being salt and light, he said, "Be perfect as your heavenly Father is perfect." And "Not everyone who says to me, 'Lord, Lord' will enter the kingdom of heaven, but only those who do the will of my Father. They will say, 'Didn't we do mighty things in your name?' And I will say, 'Depart from me, you workers of lawlessness.'"

Or maybe Christine Caine is wrong, and we should wage the good warfare lest by rejecting it we make a shipwreck of our faith. Being witnesses means that we speak truth and expose lies. Being salt and light means that we hold out the word of God and expose sin. Don't listen to anyone who tells you to just be and not do. They're liars when we understand the text.
