John Wesley on 1 Corinthians 7:31

And they that use this world, as not abusing it - Not seeking happiness in it, but in God: using every thing therein only in such a manner and degree as most tends to the knowledge and love of God. For the whole scheme and fashion of this world - This marrying, weeping, rejoicing, and all the rest, not only will pass, but now passeth away, is this moment flying off like a shadow.
