“And they that use this world, as not abusing it: for the fashion of this world passeth away.”
King James Version (KJV)
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.
1Co 7:31 They that use this world, as not abusing it. We all have to use the world; but we must not "misuse" it. That is the charge here.
