I guess nobody has ready answer to this, but if I have made God a promise, and it takes some days to fulfill it and pretty much work, what should I do on sunday? I should fulfill my promise quickly, but also avoid working on sunday and keep that day holy to God. Old days it was a sin to do any kind of work on sunday.... and christians were not supposed to show bad example of sunday working to other, not so christian people... so which is more important? Should I anyway go to church on sunday, even if my promise is not yet fulfilled and I should not fulfill it slowly (according the Bible)?
