All the friends of God ... should contribute to the extent possible, however modest their offering may be. God doth not burden a soul beyond its capacity. Such contributions must come from all centres and all believers.... O friends of God! Be ye assured that in place of these contributions, your agriculture, your industry, and your commerce will be blessed by manifold increases, with goodly gifts and bestowals. He who cometh with one goodly deed will receive a tenfold reward. There is no doubt that the living Lord will abundantly confirm those who expend their wealth in His path. (‘Abdu’l-Baha, from a Tablet, Compilation “ Agriculture and Rural Life”, prepared by the Research Department of the Universal House of Justice)
