'World' in the Bible

Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father:

to reveal His Son in me so that I might preach Him among the Gentiles [as the good news—the way of salvation], I did not immediately consult with anyone [for guidance regarding God’s call and His revelation to me].

Even so we, when we were children, were in bondage under the elements of the world:

But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.
