God is a God of promises and covenants. The biblical narrative is a story of God’s promises kept. Humans are created in his image, and thus we have biblical accounts of humans making promises to each other. The story of Ruth hinges on promises between people of different nationalities, for example (Ruth 1:16 -18). Paul references human promises in Galatians 3:15. Humans are created to be able to make and keep promises to each other.

Every financial instrument is a promise between two or more parties, and would not be possible if promises were not part of God’s creation. A mortgage loan is a promise to pay a certain amount each month. A share of stock is a promise for a portion of future dividends and a right to elect board members. In modern finance some of our promises tend to get quite complicated and detailed so it has become common practice to write them down. However, these written contracts simply reflect our created ability to make and keep promises. This ability is so central to finance that the Bible teaches us to not overpromise in our finances (Proverbs 22:26-27).
