The Blessings and Promises of Tithes and Offerings
3 Nephi 24:8–12
8 Will a man rob God? Yet ye have robbed me. But ye say: Wherein have we robbed thee? In tithes and offerings.
9 Ye are cursed with a curse, for ye have robbed me, even this whole nation.
10 Bring ye all the tithes into the storehouse, that there may be meat in my house; and prove me now herewith, saith the Lord of Hosts, if I will not open you the windows of heaven, and pour you out a blessing that there shall not be room enough to receive it.
11 And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the fields, saith the Lord of Hosts.
12 And all nations shall call you blessed, for ye shall be a delightsome land, saith the Lord of Hosts.
President Joseph F. Smith said:
“By this principle [tithing] the loyalty of the people of this Church shall be put to the test. By this principle it shall be known who is for the kingdom of God and who is against it. By this principle it shall be seen whose hearts are set on doing the will of God and keeping His commandments, thereby sanctifying the land of Zion unto God, and who are opposed to this principle and have cut themselves off from the blessings of Zion.”
