Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world--the desires of the flesh and the desires of the eyes and pride in possessions--is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever. 1 John 2:15-17
‘What is Worldliness?
Worldliness is departing from God. It is a man-centred way of thinking; it proposes objectives which demand no radical breach with man’s fallen nature; it judges the importance of things by the present and material results; it weighs success by numbers; it covets human esteem and wants no unpopularity; it knows no truth for which it is worth suffering; it declines to be a ‘fool for Christ’s sake’.
Worldliness is the mind-set of the unregenerate. It adopts idols and is at war with God. Because ‘the flesh’ still dwells in the Christian he is far from immune from being influenced by this dynamic.
It is of believers that it is said, ‘the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary one to another’ (Galatians 5:17). It is professing Christians who are asked, ‘Do you not know that the friendship of the world is enmity with God?’ (James 4:4) and are commanded, ‘Do not love the world’, and ‘keep yourselves from idols’ (1 John 2:15, 5:21).
Apostasy generally arises in the church just because this danger ceases to be observed. The consequence is that spiritual warfare gives way to spiritual pacifism, and, in the same spirit, the church devises ways to present the gospel which will neutralise any offence.
The antithesis between regenerate and unregenerate is passed over and it is supposed that the interests and ambitions of the unconverted can somehow be harnessed to win their approval for Christ. Then when this approach achieves ‘results’ – as it will – no more justification is thought to be needed. The rule of Scripture has given place to pragmatism.‘
