Hopefully making theology simpler to understand! (2 Corinthians 1:12)

“Moreover, you shall speak and say to the Levites, ‘When you take from the people of Israel the tithe that I have given you from them for your inheritance, then you shall present a contribution from it to the Lord, a tithe of the tithe.”
Numbers 18:26, ESV

God provides for ministers through His people, and the ministers still make offerings to God from that.
As Christians, we are all ministers called to support each other and help spread the Gospel.
(And when possible, have a paid, trained pastor.)
