Throughout the NEW Testament writing wherever the Church's attitude to the World in which it exists come to expression. On the one hand, the world is God's world, created by God and loved by God, currently alienated from God, it is true, but destined to be redeemed and reconciled to God. On the other hand, the world is dominated by a spirit totally opposed to God, organized in such a way as to exclude God, drawn towards unworthy goals of material status and self-interest, quite different from the goals towards which the Christian way leads.
 

John writes in his first letter; "Love not the world, neither the things, that are in the World. If any man love the world, the love of the father is not in him, for all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride o life, is not of the father, but is of the world, and the world passeth away and the lust therof: But he that doeth the will of God abideth forever". (1 John 2:15-17)
 

The Christians endure a godless world, while remaining in the "Godless World", it is uncongenial environment for the Christians; It cannot feel at home there....When the writer to the Hebrew, says that the Patriarchs of Israel Acknowledged 'they were strangers and exiles, on the earth"because, their true homeland was elsewhere.(Heb. 11:13)

This emphasis on being in the world, but not of it, involved and detached at the same- time, can be found in many parts of the New Testament.
 

This world is not my home, I'm just a pass-ing thru, My treas-ures are laid up somewhere be-yond the blue; the an-gels beck-on me from heaven's op-en door, and I can't feel at home in this world anymore, O Lord, you know I have no friend like you, If heaven's not my home then Lord what will I do the angels beck on me from heaven's  open door, And I can't feel at home in this world anymore.
