How do we know Christ's salvation is true?

The assurance of Christ's salvation comes from the unshakeable truth of Scripture, which declares that God is for His elect and guarantees their salvation through Christ. Romans 8:31 states that if God is for us, who can be against us? This powerful declaration affirms that the salvation of the believer is rooted in God's sovereign choice and the completed work of Christ. Furthermore, the narrative of Joseph in Genesis provides a typological view of Christ, demonstrating how all God's blessings and our salvation ultimately derive from Him. The testimony of Scripture assures us that Christ’s atonement is sufficient and complete, ensuring the security of believers in their salvation.
