Why is faith important in God's kingdom?

In God's kingdom, faith serves as the fundamental currency that enables believers to engage in the life and works of the kingdom. It is not a product of human effort but is a gift from God, as Ephesians 2:8-9 teaches, showing that we are saved by grace through faith. This faith acknowledges that "Christ is all" and allows individuals to receive Christ’s blessings and provisions for their needs. In contrast to the world's system, which often relies on material means, the spiritual kingdom flourishes by faith, reflecting the profound trust and reliance on Christ’s redemptive work.
