“Honour the LORD with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.”
It is great that the King James Version says “Honour the LORD with they substance,” because most other translations say wealth. It is also great that it says “with the firstfruits of all thine increase,” because most other translations say crops or produce.
It is great, because these words say so much more.
Giving it all
Allow me to paraphrase: “Give God everything of who you are and let God use you and what you have, and give God the first part of anything you get above what you have.”
This is not a prosperity gospel message, but if you honor God with what you have He will give you more. If you continue giving back when you get more, you will find your barns (or bank account or pantry or whatever) full and more than you can handle.
But it is because you are thinking about God and others, not yourself and how comfortable you are. It is because you are focused on pleasing God, not growing your portfolio or your bank account.
Jesus mentioned it, too
In Matthew 25:14-30, Jesus discusses that those who show they are good stewards of what they are given are given more. Those who sit on, hide, or squander what they are given will have it taken away. (But we must also remember that in all things “the LORD gave, and the LORD hath taken away; blessed be the name of the LORD,” (Job 1:21) must be true. Even good stewards may see everything taken away if it is for the good of the servant and glorifies God.)
The true increase and blessing is the joy of our Heavenly Father in our faithfulness and commitment to Him. We honor God because He deserves it and we love Him. We give because He gives and we love Him.
If we give simply because we expect something in return, then we should expect nothing. We are not honoring God; we are honoring ourselves.
Gracious God, Thank You for Your love and Your grace. Increase Your love in us. Give us giving hearts and a will to seek after You alone, that You may be glorified in us.
