Psalm 4:7

You have put more joy in my heart than they have when their grain and wine abound.

This is to be true of all believers. The joy that Christ has brought into our lives is everlasting and full. It surpasses any other joy known to mankind. The joy that Christ brings surpasses any pleasure of sin. The joy that Christ brings exceeds any joy that can be shared by the unbelieving and believer alike.
This is also a reminder to us of how satisfying heaven will be. No one will get to heaven and say, "this is it?" No one will think, "I was expecting something different but this will do." Right now in our family, we are anticipating a trip to Disney World. We have read many reviews of what to do with pre-schoolers. It is interesting to see how many people's anticipations were disappointed at the character meals, and various attractions. There is no chance of this being true with heaven.
In all of this we must be reminded that we should not be disappointed with our relationship with Christ here on earth either. The psalmist was not in heaven when he made this claim, but here on earth. What Christ brings into our lives in the here and now also exceeds the abundant pleasures of this earth. This phrase ought to bring conviction to many, if Christ is so satisfying, why am I craving other things? Why do I want Christ, plus what the world has to offer?
