The duty of the Christian is to bear witness to the truth. That is our role in God’s economy, in God’s plan for history in this age. The world is coming under judgment, and we as Christians must proclaim the truth of that fact.
We’re not here to build big churches. We’re not here to enjoy ourselves. We’re not here to be loved by the world. We’re not here to self-actualize. We’re here to tell the world the truth about the reality of impending judgment. The world will hate us for that and try to destroy our witness. One of the most effective ways they can accomplish that is to convince us to compromise the truth of our witness by giving in to some degree to the lies of the world. So we need to remain true, keep our witness pure and endure to the end. This is what we’re here for.
See Revelation 11.
