“There are different organizations with different propagandas to  convert people to their groups. There are lots of organizations which use  different methods to raise money. They arrange bazaar where they sell a lot  of things, they beg for money proclaiming that they are using it for the  spread of the Gospel and so on. We do not follow their methods or customs,  because we do not have room for them in the Word of God which is our  foundation. We stick to tithes and offerings as God's method of financing  His work. Some people will bring the methods of their former churches to  the Gospel, thinking that is the way things should be done. Since we know  that the Bible does not confirm it, we get away from them. We bring them  here to be taught the new method of how to spend and be spent for the  Gospel. We need money for the spread of the Gospel, to print Gospel  materials, to buy vehicles for the propagation of the Gospel, and so on.  Why should people continue to spend extravagantly on funerals,  marriages and other worldly pursuits? Whatever the believers have  belongs to God. If we spend all that we have in obtaining all the material  things that will be burnt up by God in the end, what will be our reward in  Heaven?  

“But the day of the Lord will come as a thief in the night; in the  which the heavens shall pass away with a great noise, and the elements  shall melt with fervent heat, the earth also and the works that are therein  shall be burned up” (2 Peter 3:10).
