One popular Bible verse often used to encourage church members in their giving is Malachi 3:10 (NIV):
"Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this,” says the LORD Almighty, “and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it."
This verse emphasizes the importance of tithing and the blessings that come from faithful giving.
