What assurance do Christians have of eternal security?

Eternal security is a vital aspect of the believer's relationship with Christ, offering assurance that once God saves an individual, that salvation is secure forever. John 10:28-29 emphasizes this by affirming that Jesus' followers are held firmly in His grip, promising that no one can pluck them out of His hand. This doctrine reflects the sovereign grace of God, affirming that it is not reliant on human effort or decision but on the unbreakable commitment of Christ to save and keep His people. As Romans 8:38-39 declares, nothing can separate us from the love of God, further confirming the certainty and permanence of eternal life for those who are truly in Christ.
