<p>7:31- see on 1 Cor. 9:18.</p><p><em>And those that use the world, as not using it to the full. For the fashion of this world passes away</em>- Marriage and all that goes with it is a using of the world. But we are not to be obsessed with these matters of human existence, learning the lesson from the world of Noah's day. We are not to use the Lord's concessions to our humanity &quot;to the full&quot; in becoming obsessed with them. &quot;The fashion of this world&quot;, the external condition Gk., shall pass away. Whilst essential relationships between persons shall eternally remain, all else, including marriage, shall pass away. And we are to set our hearts on those things which are eternal. The present tense &quot;is passing away&quot; reflects Paul's sense of the closeness of the Lord's coming; and John uses the same words in saying that this world with all its desires, including for marital relationships, passes away (1 Jn. 2:17). The world and all in it has the semblance of permanence; but this too shall pass. Truly the things that are seen are temporal, and only the unseen things are eternal (2 Cor. 4:18).</p>
