This is the day that the Lord has made, we will rejoice and be glad in it. — Psalm 118:24 (NKJV)

And this from Phillip Yancey:

Some of us seem so anxious about avoiding hell that we forget to celebrate our journey toward heaven.

I love that song.  Especially the SKA version I heard about 8 years ago.  The racous music and rough singing was at contrast to the lyrics, but that was what made it unique.  As is each day we live in the Lord, each uniquely made for us to enjoy, and be glad for.
