For,In answer to the previous post, the way knowledge of imperishable should affect your life is in this way. It is the realization that we are just about as durable as grass.
"All men are like grass,
and all their glory is like the flowers of the field;
the grass withers and the flowers fall,
For what is our hope or joy or crown of boasting before our Lord Jesus at his coming? Is it not you? (1 Thessalonians 2:19 -- ESV) Three things mentioned here... "hope" ... "joy" ... "crown of boasting" ... Hope - What does Paul have his sights set on? Joy - What is it that brings Paul joy? Crown of Boasting - That Olympic Wreath of Glory that is placed on his head? It is these people. It is his children in the faith. They are Paul's Hope and Joy and Crown of Glory when Jesus returns.
