Ecclesiastes 11:7-10
7. Light is sweet and it pleases the eyes to see the sun.
8. However many years a man may live,
let him enjoy them all.
But let him remember the days of darkness for they will be many.
Everything is meaningless.
9. Be happy, young man, while you are young,
and let your heart give you joy in the days of your youth.
Follow the ways of your heart and whatever your eyes see,
BUT know that for all these things God will bring you to judgement.
10. So then, banish anxiety from your heart,
and cast off the troubles of your body
for youth and vigour is meaningless.
