Proverbs 3:9-10 (KJV)
9 Honour the Lord with thy substance, and with the first fruits of all thine increase:
10 So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.
The word of the Lord instructs us to give tithes, which is 10% of our increase. This instruction is for all Christians. Not some Christians, all Christians. In the text above we see that we are to honor the Lord with the 1st of all of our increase. This means, we are to pay the tithes on the gross, not the net. In doing so, the word says our barns (houses) will be have plenty. Do want to have plenty? I know I want to have plenty.
