'In the World' in the Bible

He was in the world, and the world was made by him; yet the world knew him not.

While I am in the world, I am the light of the world. Having said this,

Now before the feast of the passover, Jesus knowing his hour was come to pass out of this world to the Father, having loved his own who were in the world, loved them to the end.

I have spoken these things to you, that ye may have peace in me. In the world ye shall have tribulation; but take courage: I have overcome the world.

And I am no longer in the world, but these are in the world, and I come to thee. Holy Father, keep thro' thy name them whom thou hast given me, that they may be one, as we are.

While I was with them in the world, I kept them thro' thy name. Those whom thou hast given me I have guarded, and none of them is lost, but the son of perdition, that the scripture might be fulfilled.

And now I am coming to thee, and I speak these things in the world, that they may have my joy fulfilled in them.
