The Bible talks a lot about bringing God your “firstfruits”. To bring your firstfruits means to give God the best of your efforts. In terms of finances, it means you give back to God before spending anything on yourself. In Scripture, it amounted to dedicating the first growth of your crops, or the first born from your flocks and herds, and even your family.
You give back to God first, and the remainder is for your blessing. These days, we don’t often give God our firstfruits. More likely we give Him our leftovers and expect Him to bless us abundantly in return. This is embarrassing at best, but I must admit my own guilt in this area.
