Living in France, we would be surrounded by Frenchmen. Same goes with living in Germany. Wherever we live, we are surrounded by the people who also live there. Looking at the big picture, we live in the world surrounded by worldly people who believe worldly things and are greatly influenced by the worldly way of life. It is almost impossible not to be affected by the world since we do live in it. As a Christian, God expects us to live in the world but not be apart of it. Can we live a church? (there are worldly problems there also) Should we live underground and be sheltered from the world? No, God commands us to “do everything without complaining or arguing, so that you may become blameless and pure, children of God without fault in a crooked and depraved generation, in which you shine like stars in the universe” (Philippians 2:19).
We must live among the worldly people yet be an example for Christ. Once you surrender your life to God, He will make you “shine like the stars”. You will be the smiling face in the crowd, you will be the one everyone needs to talk to about problems because somehow you seem to have it all together. It’s a tremendous responsibility and honor to be one of God’s chosen stars. In fact, it will be a bit troubling because as you see worldly things happening to “so-called” Christians, you are responsible to call them on it. God will not be mocked or have the bad reputation because of a worldly decision you make. You will be judged harshly.
Paul spells it out completely in 1 Corinthians 5:9-12 “I have written you in my letter not to associate with sexually immoral people—not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. But now I am writing you that you must not associate with anyone who calls himself a brother (Christian) but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat. What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. ‘Expel the wicked man from among you’”.
Doesn’t get much clearer than that!
