But when they measured it with an omer, whoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat.
Exodus 16:18

This is a statement about salvation, not economics. The manna is a picture of Messiah #yeshua. There was no work involved in collecting the manna. You just had to walk outside and scoop it up. You could work more if you wanted, but you'd never get more manna no matter how much you worked. Salvation is a free gift available to anyone willing to accept Yeshua's proposal. More obedience or getting "more #Jesus" won't make you any more saved.
