Why is the doctrine of election important in Christianity?

Election is a fundamental tenet in Reformed theology, derived from passages like Ephesians 1:4-5, which states that believers are chosen in Christ before the foundation of the world. This doctrine emphasizes God's sovereignty in deciding who is saved, showcasing His grace and love towards the elect. Understanding election gives believers assurance that their salvation is entirely dependent on God's purpose and not on their merit. This leads to a humble gratitude, compelling them to share the gospel, as they recognize that it is by God's grace that they have come to faith.
