I do not mean that others should be eased and you burdened, but that as a matter of equality your abundance at the present time should supply their want, so that their abundance may supply your want, that there may be equality. As it is written, “He who gathered much had nothing over, and he who gathered little had no lack.” 2 Corinthians 8:13-15
“It is true that giving should not cause a hardship to the givers. But at the same time, a person ought not to keep more than he needs for himself.”
