There is definitely no reason to "cave in" because of Jesus' words to us in John 16:33:
"I have told you these things, so that in Me you may have [perfect] peace and confidence. In the world you have tribulation and trials and distress and frustration; but be of good cheer [take courage; be confident, certain, undaunted]! For I have overcome the world. [I have deprived it of power to harm you and have conquered it for you.]" (Amplified Bible)
We need to trust God - the benefits are clearly stated in Psalm 1:1-3.
God expects that we bear fruit in any and every season – irrespective of what is happening within or around us. Do you remember the story about the Carrot, Egg & Coffee (http://sapphire-and-beryl.blogspot.com/2010/11/are-you-carrot-egg-or-coffee-bean.html)
God doesn’t expect us to judge how others (i.e. teabag, carrot or egg people) respond to their "hot situations" He just expects us be an example, a consistent one and people will be drawn to His light in us as Isaiah 60: 1-3 says: "Arise [from the depression and prostration in which circumstances have kept you—rise to a new life]! Shine (be radiant with the glory of the Lord), for your light has come, and the glory of the Lord has risen upon you! For behold, darkness shall cover the earth, and dense darkness [all] peoples, but the Lord shall arise upon you [O Jerusalem], and His glory shall be seen on you. And nations shall come to your light, and kings to the brightness of your rising. (Amplified, italitics mine)
"Here’s another way to put it: You’re here to be light, bringing out the God-colors in the world. God is not a secret to be kept. We’re going public with this, as public as a city on a hill. If I make you light-bearers, you don’t think I’m going to hide you under a bucket, do you? I’m putting you on a light stand. Now that I’ve put you there on a hilltop, on a light stand—shine! Keep open house; be generous with your lives. By opening up to others, you’ll prompt people to open up with God, this generous Father in heaven." (Matt 5: 14-16; Message)
