When you obey God’s Commandments, like giving your Firstfruit, God calls you righteous
By returning the Tithe and giving your offerings towards the Work of the Ministry, you’re managing His Resources on His Behalf.
The Lord Jesus Christ teaches us that if we want to be trusted with more, we should be faithful with what we already have
When you give less than 10%, that's an offering. When you give 10%, that's your Tithe.
