What Profit?

Because all men die, the writer of Ecclesiastes laments: What profit hath a man of all his labor...? (Ec 1: 3) Noting that the eyes of man are never satisfied (Ec 1:8; Pr 27:20), he concludes that all is vanity.
How are the eyes "never satisfied"? First Jn 2:15-17 states:
Love not the world...For all that is in the world...the lust of the eyes...is not of the Father, but of the world...And the world passeth away.
Outside of God's redeeming grace, humans will lust after whatever their eyes see that is appealing. Eve lusted after the fruit that appeared attractive to her. Earthly possessions pass away. Mark 8:36 asks:
For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
Solomon in Ecclesiastes 1-2 reflects on the meaninglessness of life when viewed without an eternal perspective. He concludes that even the profitable life and the life of pleasure is vanity and of no real enduring profit. Love of the world is not of the Father. Solomon did great works and "whatever mine eyes desired I kept not from them" (Ec 2:10). He had everything anyone could want, but he found life without God was meaningless.
How many individuals today are too busy (or just unwilling)to recognize the meaninglessness of their efforts aimed at satisfying the "lust of the eyes," which can never be satisfied? Solomon calls it vexation of spirit or grasping for the wind. The Lord has an answer to the meaningless life, but the individual has to recognize the meaninglessness of his efforts first.
