We Christians are as G.K.Chesterton put it, "the most materialistic of religions".
When we reject a crude hedonism that is never satisfied with the material goods it has, it is because we think the things we already have are such wonderful gifts that we should treasure them rather than lusting after more.
We praise God for beauty of a Sunset over a forest or a cascading waterfall. We say grace to give thanks for the food we eat. We rejoice in the birth of a baby. We think the world we live in is something good - a gift to us from God.
