"And they that use this world, as not abusing it; for the fashion of this world passeth away." 1 Corinthians 7:31
Nothing is real but that which has an abiding substance. Health decays, strength diminishes, beauty flees the cheek, sight and hearing grow dim, the mind itself gets feeble, riches make to themselves wings and flee away, children die, friends depart, old age creeps on, and life itself comes to a close. These fugitive, transitory things are then mere shadows; there is no substance, enduring substance in them. Like our daily food and raiment, house and home, they support and solace us in our journey through life. But there they stop; when life ends, they end with it. But real religion—and by this I understand the work of God upon the soul—abides in death and after death, goes with us through the dark valley, and lands us safe in a blessed eternity. It is, therefore, the only thing in this world of which we can say that it is real. Is not this John's testimony? "All that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof; but he that doeth the will of God abideth for ever" (1 John 2:16, 17). And who is that man, that blessed man, who lives when all dies, who abideth for ever when all others pass away into the outer darkness? It is he who doeth the will of God. But how and when do we the will of God? "And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day" (John 6:40). If, then, you have seen the Son, and believed in him, you have now everlasting life, and Jesus will raise you up at the last day.
