The world's attitude towards Christians is often based on the Christian's attitude toward the world (people, not worldliness).
The world loves Christians who are sincere and selfless; they love Christ in us, until they harden their hearts against Christ.
We are either a sweet smelling savor or a stench. Don't be a stinker.
2 Corinthians 2:14-17
(14) Now thanks be unto God, which always causes us to triumph in Christ, and makes manifest the savor of his knowledge by us in every place.
(15) For we are unto God a sweet savor of Christ, in them that are saved, and in them that perish:
(16) To the one we are the savor of death unto death; and to the other the savor of life unto life. And who is sufficient for these things?
(17) For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
