If you borrow 4B and you make 7B or 8B or even 10B,then you shall have made a profit from the loan and that would be super!
Problem comes when you make losses from the loan! That would be tragic!
But you shall remember the LORD your God,for it is He who is giving you power to make wealth,that He may confirm His covenant which He swore to your fathers,as it is this day. Deu 8:18
