How do we know that God's salvation is secure?

The assurance of salvation comes from understanding that Christ's atoning work completely satisfies the demands of divine justice. In Hebrews 9:28, it highlights that Christ appeared once to bear the sins of many. Through His substitutionary sacrifice, He guarantees the salvation of all whom the Father has given to Him. Furthermore, the Scriptures affirm that nothing can separate us from the love of God, ensuring that our eternal standing is not dependent on our performance but on Christ's faithfulness and righteousness. This profound truth enables believers to live with confidence in their salvation.
