I think there's a natural law on giving, as seen in Luke 6:38
Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give unto your bosom. For with the same measure that ye mete withal it shall be measured to you again.
I think Paul's message was built on this law, spoken by Christ.
The thing many don't realize is that this law applies to both good and bad gifts.
Indeed.
Blessings Sister, have a bountiful day.
