What some may call Karma this what the bible calls "sowing and reaping"
We've all heard the saying "what goes around comes around" but that phrase comes from the bible Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the Lord , till he come and rain righteousness upon you.
This is also a core principal for giving.
There is one who scatters, yet increases more; And there is one who withholds more than is right, But it leads to poverty. The generous soul will be made rich, And he who waters will also be watered himself.
Proverbs 11:24-25 NKJV
Therefore, the secret to true wealth is sow a seed and you'll reap a harvest.
