The investor must give by faith. It’s not a faith in “faith,” but a faith in God—that God will see and respond. “Without faith it is impossible to please God,” Hebrews 11:6. When we give generously by faith, we don’t know how and when God will “repay,” but He certainly will. God’s blessing is a promised reward for faith-based obedience. A “payback” is real and assured, but the specific form/quantity/media are not predictable. The blessings for faith-based obedience can take an endless number of expressions—even beyond our comprehension.
