Self glory makes life meaningless, glorify God fulfills it

Whatever we have in the glory of man is "away". Those are just not enough before we go "home" to the glory of God.

Yesterday I was clever, so I took the glory for me. Today He makes me wise, so I give the glory to Thee

Wasting time is living in self glorification instead of glorifying God as God is time

Religiousity is unself glory not purity

What "wasting time" means? At the time we glorify self instead of glorify God, at that time we are wasting our time as... God is Time.
