Another question has come up from a person named Mark.
If I want to donate to a house building ministry to cover the cost of materials to build the house, and go to Mexico to do the work, can that be my tithe? I can not afford to give my church my 10% next month and the house building for the poor all in the same month. I have committed to the Mexico trip.
First things first. You are not required to tithe (10% minimum). I don’t want to go into much detail about that, since there is so much information not only on this website but on so many others as well.
It seems that the Spirit has put a burden on your heart to help the people in Mexico. Do not suppress the Holy Spirit’s conviction on your heart. I cannot directly tell you what you should do with your giving. I would definitely say it’s not worth getting into debt over the matter. If you feel that the Holy Spirit is asking you to give both to Mexico and your church, then find ways you can sacrifice in order to pay both. I don’t know if it would be selling something, or fasting through a couple of meals to save money.
It is great news to hear that your heart is opened to the conviction of giving from the Holy Spirit and not from a law that is dead. The Spirit is alive in you, so follow the calling from the law that is living in you instead of the law of tithing that has been dead for 2000 years.
