Living as if we were already in heaven

When reading Psalm 100 today, it struck me that it describes what life in heaven will be like.

We will shout triumphantly because of the victory that we have in Jesus. (Psalm 100:1)

We will serve the Lord with gladness.

We will come before him with joyful songs. (2)

We will acknowledge and rejoice in the fact that we are his. (3)

We will enter his presence with thanksgiving and praise. We will bless his name. (4)

For he is good, his faithful love endures forever, and his faithfulness to all generations. (5)

What an awesome depiction of heaven!

But why wait for heaven? Why not live that way each and every day?
