You have to understand that when Abram payed his tithe to the King if was his first 1/10(first fruits)
God was not happy with Cain’s offering because it wasn’t his first 1/10.
Tithing is a spiritual issue and God will have to work in your heart there is nothing I can do for you, but pray that you will be revealed the truth in his word.
