The post can duel in this sub board or in the economics board. Anyone will do.
The saying "Givers never lack" is a popular saying gotten from the bible. With Christianity it is believe that if you give, you will get it back in thousand folds but the truth of the saying is, God will never let you lack, it was never about humans giving you back in return. Many misunderstand that word, so they expect when they are in need, that they deserve someone to give to them too.
Yes I think the gospel preaches it and so it is indeed a reality of life but when you give, you may expect your manna to come not from a man or expecting returns from those you helped.
That should be what your bible explains to you.
As I have also been experienced, being successfully favoured in that mysterious ways could be as a result of your offerings in acocunts to how you have been of help to others.
So the grace of giving rewards rewards you. I also heard generous givers never lack.
