In the first letter of Paul to Timothy, the apostle writes "For everything created by God is good, and nothing is to be rejected, provided it is received with thanksgiving; for it is sanctified by God's word and by prayer."
I admire the newly converted: with rigor and enthusiasm, they take on new challenges. They examine the profane and irrelevant with a sensitive and severe eye. They establish high standards for themselves and for others. The faith is reinvigorated with their expectations and energy. They are attentive to whatever endangers their new-found faith. They reject the terrible things in their past that distracted them from their faith.
Paul tempers such a view. For sometimes the rigorous, while useful, take a dim view of the good things God has created. They know well the dangers of sex and food and pleasure; but in doing so divide themselves from the life God has given. Our lives are abundant and rich due to the material creation arisen from God's breath. To assume that it is corrupt is to look in the wrong place. The place where we begin to fall short is in our own hearts, where we think that our desires are God's desires.
It's easy for us to assume that what we don't want is what God doesn't want. The response that Paul says is that its all good - in itself. As Jesus said, wickedness comes from the human heart. Chocolate, the occasional whiskey, a dance or a game of cards - all can test the soul. But in themselves, they do not contain sin. Sin lies squarely with our amazing ability to assume that our God destroys and judges on our personal behalf.
