Malachi 3:10 (c) We are not to believe that this refers to any local church, for it does not. Israel had only one center of worship, at the temple. The reference evidently is to the Church of GOD in all its wideness and fullness. We are to invest in GOD's work and GOD's business wherever we see the need. We are to place our funds where they will be used for the salvation of souls, and the upbuilding of the saints. This does not need to be only in our own denomination. Of course, the first obligation we should fulfill is to the local work with which we are identified. There is no Scripture at all, nor suggestion, that all the money which is given by GOD's people should be put into one basket to be spent by others.
