How is salvation achieved according to the Bible?

The Bible teaches that salvation is a gift from God, accomplished through the atoning work of Jesus Christ. Ephesians 2:8-9 emphasizes that it is by grace we are saved through faith, not of ourselves—salvation is the result of God's mercy, not our own efforts. Christ's sacrificial death satisfied divine justice and secured redemption for His people. This means that believers do not contribute to their salvation but instead receive it with humble gratitude. Therefore, faith itself is also a gift from God, ensuring that all glory for salvation goes to Him alone.
