'World' in the Bible

This saying is trustworthy and deserving of full acceptance: “Christ Jesus came into the world to save sinners”—and I am the worst of them.

And most certainly, the mystery of godliness is great:He was manifested in the flesh,vindicated in the Spirit,seen by angels,preached among the nations,believed on in the world,taken up in glory.

For we brought nothing into the world,and we can take nothing out.
