Why is understanding limited atonement important?

The doctrine of limited atonement is critical as it asserts that Jesus's atoning work was intended for those whom God elected. This belief provides assurance that Christ's sacrifice is fully sufficient for the salvation of His people, reinforcing the idea that our faith and salvation are entirely dependent upon God's grace and not our own efforts. Ephesians 1:4-5 illustrates God's eternal purpose of grace toward the church, affirming that Christ's sacrifice is effective in achieving the salvation of those chosen before the foundation of the world.
