How do we know salvation is secure for God's elect?

The security of salvation for God's elect is a fundamental tenet of sovereign grace theology. As demonstrated in John 6:39, Jesus states that He will lose none of those given to Him by the Father, which reassures believers that their salvation is not contingent upon their own merits but on God's powerful will. 1 Timothy 1:9 reinforces this by indicating that our calling and salvation were not based on our works but according to God's purpose and grace, established before time began. The belief that those whom Christ has redeemed will be raised on the last day establishes a profound peace for believers in knowing their eternal destiny is secure in Christ's completed work.
