For what is the world?
It is the system that Satan planted amongst fallen men to blot out the memory of a lost paradise; and it has gone on enlarging, embellishing, and progressing ever since, in spite of the awful catastrophe of the deluge, until it rose up rebelliously against the Son of God and crucified Him on the tree.
This is at length what the world did, with all its arts and letters, its religion and philosophy.
The world then consisted of both Jew and Gentile. They both loved the world, and they both united in rejecting with the utmost ignominy the Lord of glory.
Is the world then an object for a Christian's love? or anything that is part and parcel of the world? anything that is its boast and its delight? Is it not treason against the Father and the Son?
