The Gospel is free of charge

Matthew 10 vs 8

Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.

Jesus Christ called His disciples and sent them to preach the Gospel.
He also charged them not to demand money for signs and wonders they performed in the name of Jesus Christ.
He told them to heal the sick and lepers, raise the dead and cast out the demons.
He told them not to charge a fee for preaching the Gospel because Jesus Christ did not charge a fee when he gave them anointing, Holy Ghost, and power.
Any minister that charges a fee for preaching the Gospel has missed his callings.
If you are not ready to preach the Gospel free of charge, look for another job.
However, it is not out of place to receive tithe and offerings from anyone that follows the Gospel
