Genesis 12:2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
First, when God said "I will bless thee" it is to improve your standard of living first not your giving. You have a family & you have responsibilities. So you first before any other. Remember God said "I wiill bless thee .....and thou shall be a blessing."

I don't know what's your take on this?
But for me I totally disagree with the write up below.
