In the beginning God called everything in his creation good. From the genesis of man, he began drawing boundries around the things he thinks are good and called everything outside those boundaries evil. Thus was the birth of religion (the concept of good and evil) designed by man to control and to deprive man from all of the good God had created.
It is the blessing of God for humankind to eat, drink and enjoy the fruit of their labor, to enjoy this short life he has given us. God has called us not to think too much (worry) but instead, to enjoy the present because he has given us joy as an antidote for our cares. Life is but a gift and who can't enjoy a gift? Those who think and worry to much about whether they are being good or bad based on the boundries of men not of God.
God created everything and called it good and gifted us with life and the hope that we will chose to enjoy the gift of life, though short and tragic, and to find contentment.
Laugh, love and live, that is the desire of God.
