'World' in the Bible

For the reason for our boasting is this--the testimony of our own conscience that it was in holiness and with pure motives before God, and in reliance not on worldly wisdom but on the gracious help of God, that we have conducted ourselves in the world, and above all in our relations with you.

We are to tell how God was in Christ reconciling the world to Himself, not charging men's transgressions to their account, and that He has entrusted to us the Message of this reconciliation.

For godly sorrow produces repentance leading to salvation, a repentance not to be regretted; but the sorrow of the world finally produces death.

For, though we are still living in the world, it is no worldly warfare that we are waging.
