Malachi 3:8–12 promises a curse upon those who fail to tithe. To preach the tithe to Christians today is to preach the possibility that even after all of their sins are wiped and all of Christ’s righteousness is imputed to their account, they can somehow still be accursed because of their failure to tithe. So much for grace. Preaching the tithe to Christians is a rejection of the Gospel. There, I said it.
