JMNT(i)
15 You folks should not be habitually loving (as indicative: are not normally accepting; as imperative: Stop constantly seeking reunion with) the world (secular realm and the controlling ordered System of culture, religion, economy and government), neither (or: not even) the things within the world (ordered system). If anyone is in the habit of (or: keeps on) loving the world (ordered system of religion, or of secular society), the Father's [other MSS: God's] Love (or: the love which the Father has; the Love which is the Father) does not exist within him,
16 because everything within the world (ordered but dominating System of the secular and the religious) – the flesh's over-desire (full passion of the alienated human nature; lust of the estranged self; earnest wants of the false persona that was conformed to the System), and the eyes' over-desire, and the arrogant ostentation (haughty, presumptuous or pretentious egoism) pertaining to living (= the biological and sociological life we live), is not out of the Father as a source (or: does not proceed from the Father), but rather is continuously forth from out of the world (the ordered System of society, culture and religion),
17 and the world (ordered System of religion, society, culture, economy and government) is progressively (or: constantly; repeatedly) being caused to pass along (pass by; pass away), as well as its over-desire (full passion; earnest wants; lust), yet the person constantly doing (or: performing) God's will (intent; purpose; desire) remains (abides; dwells) on into the Age (= the time and sphere characterized by the Messiah).
