As an estate planner formerly, my pastor would counsel people how to handle their retirement money: Give it all to your children now, before you die, because if you wait, the government is going to get a bunch of it.
As much as people didn’t want 
Uncle Sam to gobble his unfair share, they would always balk. They want to make sure they have enough in case they get sick. Or whatever. Inevitably, the IRS trundles away with the kids’ inheritance.
There is a lesson for us Christians: don’t hold back on giving to God. Only what you give is credited to your account in Heaven. Don’t wait for another day, a better offer, a wider safety margin. Because the devil is going for his oversized slice of the pie. Give it recklessly (that is, with faith). Throw caution to the wind and your money to the offering plate. God is able to keep you from the rainy day for which you are saving.
