In such a world, Christians should be labelled "Dangerous".
Danger: here comes a person to whom the Word and the Way of the God of the Bible is important. We've seen in our home group material over the last few months that God specifically placed His people at the cross roads of the world in order to show how a people under God live. This morning John reminded us of some OT laws that, when obeyed, shine light into the world around us. God placed His people where He did in order to be a shining light to the nations. In Leviticus there is a law which says: "Use honest scales and honest weights, an honest ephah and an honest hin. I am the LORD your God, who brought you out of Egypt" Travellers would have learnt that when you passed through that part of the world, you didn't have worry about being ripped off. God's people reflected God's glory ... they were people of integrity ... there Yes meant ... Yes. Christians are God's people today, we are made to love and to reflect His glory; and we are "dangerous" to the 21st century world because we are people to whom the Word and the Way of the God of the Bible are still important because the Word Himself said:
People who are this light and this salt are "dangerous" people in today's world. Danger! ... this person will audit your tax return differently to the one who says: "I think you'll get away with that expense claim"
Danger! This politician will actually do what he said he would do, even if it means he loses his seat at the next election ... or goes against the party whip.
Danger! This person will actually speak out against injustice.
Danger! This person will not tolerate gossip, so you better stop when they walk into the room.
Danger! This person is, in the words of Jesus, "light to the world" ... she will shine light on any darkness she uncovers and bring it into the light.
Danger! This man is, in the words of Jesus, salt of the earth. He will attempt to prevent rot and decay from spreading.
