Proverbs 21:17. (ESV)
17 Whoever loves pleasure will be a poor man; he who loves wine and oil will not be rich.
If you love something so much that it takes away your ability to be responsible, then this becomes a problem. Let's take it a step further: If you have a guilty pleasure or "responsibility" that hinders your ability to tithe and put God first, then this entity has become your god and could be blocking your blessing. Further more, if you love something enough and cannot save due to it, then it has taken away your ability to be responsible. Let's pray that we find balance and get away from over-indulgence. Most importantly, that we put God first, which will allow the rest to fall into place.
