No, God is honoured during the day. During the night we are free to enjoy the bounty of His creation.
I know, it's a bit silly that some actually fatten during Ramadan, but as long as they follow the rules on fasting to the letter during the day, I cannot condemn them. Fasting from dawn to dusk still takes a significant level of dedication.
"to the letter". Therein lies the rub.
Fundamentalisms, following things to the letter, only invites legalism. When we follow things to the letter, we read Scripture like a lawyer scanning a contract for loopholes. Is there love in an adversarial relationship with God? Where He tells us what we must do and what we cannot do, and we try to justify doing what we want to anyway, all the while minding the strict letter of the law.
I'm a lawyer, that is what we do. "Woe unto you, you lawyers" Christ said. "For the letter of the law killeth, but the Spirit giveth life".
Reading for the spirit of Scripture, reading the words with a spirit of love, is a different thing. Love does not allow loopholes. If you love your mother, and she is ill and sends you to the corner store to buy aspirin, you do not give up and go home because the specific store she sent you to is closed. You go and search until you find what she needs.
And if you bring your sick mother ibuprofen and not aspirin because that is all there was to buy, she does not say "I said a-s-p-i-r-i-n!" but she knows that you did your best for her.
Love is complicated, full of give-and-take, sacrifices and tough choices. If your friend is an alcoholic, you might change your plans for your birthday party so as not to lead your friend into temptation. Your other friends might disagree.
Love requires freedom, not "do it my way or I'll have to bust out with the other thing" to paraphrase C.S. Lewis. We might discipline our children, we might have to tell a friend some harsh words, but it breaks our hearts to do so. Remember what C.S. Lewis said about moral choices and theosis (Rusmeister,
I am tagging you in here!)
Love is more interested in what is in your heart than in results. If you fast or give alms in order to look like a holy dude, than it is for all naught. "Let not your left hand know what your right hand is doing." Regardless of the results achieved. Because it is not concerned with results or metrics, love cannot be shortchanged. You cannot pray five times a day and call that enough. For love, there is never enough.
Rules are easy. Love is hard. Which makes it much more real.
