Even if a person is young and vibrant, what is important is,
'How much his mind and actions are directed toward the heavens.
How much they achieve salvation and how much they try to live to fulfill God's Will.'
Only that mentality and actions are the power of self-sustenance
and functionality that achieve salvation and fulfill God's Will.
The rest of the mentality and actions that were used for the world were not
things directed toward Heaven.
