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

The security of salvation for God's elect rests firmly on the completed work of Christ, who purged our sins and secured righteousness for those called by Him. In Philippians 3, Paul explains that true believers—those who worship God in spirit and rejoice in Christ—have no confidence in their flesh, affirming that their salvation is not dependent on personal achievements or adherence to the law. Instead, it is established on faith in Christ's righteousness. This certainty is further affirmed through the assurance provided by the Holy Spirit, who confirms to believers that they belong to God and are safe in His grace. Ultimately, salvation for the elect is a testament to God's unchanging promise and the effectiveness of Christ’s sacrifice.
