If they will rob Yahuah chances are they will rob you! It's important in these days that we start teaching how to come out of poverty instead of just enabling them to stay there.
It starts with them doing as it says in Malachi 4 with whatever they have to bring their tithes and offerings into the storehouse and testing Yahuah.
Those who've already been through this death to self and money knows the importance of this process.
