Exodus 22:29 “You shall not delay to offer from the fullness of your harvest and from the outflow of your presses. The firstborn of your sons you shall give to me.

Setting our giving ahead of our spending is God-honoring. The problem is that giving is often based on what is left over rather than at the beginning. This is a good indication of where the importance of honoring and glorifying God has been placed in our hearts and minds. God loves a cheerful giver and one that gives out of a heart-filled desire to honor and glorify Him. It is not out of our abundance we are to give. It is the first of whatever we have. There is so much that could be said about our culture that places things of God second, third, or fourth in our daily lives. Giving is a good indication of where God is placed in our hearts. Choosing to honor and glorify God with the first of our fruits or our labor will impact our hearts. It places all things we have in light of the Giver of all things. Setting aside our first fruits with an intentional choice to give them in honor and glory of God is good for our souls. If you want more treasures in your heart for God when you die, give more while you live.
