God gave us planet earth, all the animals, and all our ingrained pleasures like . Sin is generally thought of as twisted the good things God gave us. Here's and idea of how we twist them: we think that we control the pleasures, so using them is an act of victory, and exercise of power. This makes us want to use these pleasures even when they are no longer beneficial to us. This is why gangs fight over 'turf'. This is the essence of power-mongers, spontaneous bullying, s, etc.
If these pleasures (well, some are pleasures) are gifts, then we don't abuse them. Why? Because we are more confident in our ownership of them. Hm... We don't have to exercise them to own them anymore. We don't have to 'conquer' and use pleasures in order to own them. The gifts are for our pleasure, not our strength, so if they don't give us pleasure anymore, then we don't use them anymore.
I got this idea while eating a blizzard at DQ. If I consider this blizzard to be a treat that I earned then I feel a need to enjoy it, and I'll probably end up not enjoying it as much. If fact, when I eat my way down to a disgusting part, or if I get full, I'll keep going because I earned it and I want to enjoy what's rightfully mine.
However, if it's a gift. (which it was, my Mom took us out for ice cream - I love you mom!) then I don't need to eat all of it. I feel kind of obligated to enjoy it because she gave it, but if I really don't enjoy it, then I'm just a little sad that she wasted some of her money.
Note that this way, as a gift, I don't feel inclined to grab the reward before the proper time. If it is a true gift, then I know that the giver desires my happiness, and the gift will be better enjoyed at the proper time. This has a fairly strong application to .
